Let"s look to the regular table because that our answer! The periodic table tells us information about every aspect in visibility in that neutral state. The neutral state of an atom is as soon as it"s net fee is zero; that is, the number of protons amounts to the number of electrons. Oxygen is the eighth element in the regular table, with the prize O. This means that it has eight electrons in the neutral state. Since it is neutral, it additionally has eight protons!

The routine table has one more number connected with every element, and also that is it"s atomic mass.

You are watching: How many neutrons does oxygen have in its nucleus

for oxygen, the atom mass is 16 AMU (Atomic fixed Units). In regards to mass, protons and also neutrons have about the very same mass, and also electrons have actually very little mass in comparison. Protons and neutrons each count for one AMU, and also the electron counts because that zero AMU. So, if the atomic mass the oxygen is 16, that means we have a total of 16 protons and neutrons. 16 complete protons and neutrons minus 8 protons pipeline us v 8 neutrons.

This calculation can acquire surprisingly tricky! The atomic mass the an element is an median over every one of the isotope of each element. An isotope is an element that has a different variety of neutrons in different atoms. The chemistry properties that the aspect don"t change, but the atomic mass the the element is various if that has, say, 8 neutrons matches 9 neutrons. Due to the fact that the atom mass the each element is averaged over every stable isotope of the element, occasionally we check out decimal numbers for the atom mass. For example, the atomic mass the carbon (the 6th element top top the routine table) is 12.01 AMU. This tells us that most carbon atoms have actually 6 protons and 6 neutrons, and some carbon atoms have 6 protons and also maybe 7 or 8 neutrons.

Most carbon atoms have actually 6 protons and 6 neutrons, therefore the atomic mass is very close to 12 AMU. Researchers have uncovered the loved one abundance of every element and isotope, so we canlook up how common an isotope is. For oxygen, the isotope with 8 protons and also 8 neutrons makes up 99.7% of all oxygen atoms, so its a for sure bet come say that oxygen almost always has actually 8 protons and 8 neutrons.

Answer 2:

I"ll begin by comment the question directly: in general, element oxygen has 8 protons, 8 neutrons, and 8 electrons. Your concern is an exciting one, due to the fact that it is often the beginning point for countless other inquiries we have the right to ask about elements, chemicals, and materials.

For instance, though we regularly refer to the gas us breathe as simply "oxygen", the is in reality the molecule O2 (two oxygen atoms bonded together).

The reason for this has to do with the number of electrons oxygen has. Electrons have a certain means of arranging themselves on atoms, and also we have the right to think the electrons together existing in "shells" roughly the atom"s nucleus. For currently we have the right to think of atoms as having "inner" and "outer" shells. Oxygen has an inner covering that deserve to hold 2 electrons, and an outer shell that have the right to hold 8. Shells space filled from the innermost to the outermost, so since oxygen has actually 8 electrons, we placed 2 in the inner shell, and also the remaining 6 in the outer shell. as we have the right to see, there"s still two empty spots for electrons to go in the external shell (which deserve to hold 8), and also the oxygen would really choose to to fill those spots. The does this in a clever way; the looks for a partner! If 2 oxygens acquire together, they have actually 16 electrons total. By "sharing" 4 of them, lock each get to "keep" half of the continuing to be electrons (16 complete - 4 shared = 12 remaining, 12/2 = 6 each). On each oxygen, 2 of this 6 walk in the inner shell, and the various other 4 walk in the outer shell. Now, the oxygens relocate close together, and they share the 4 remaining electrons the they didn"t "keep". This method they both gain to feel like they have actually a full outer covering (4 that they need to themselves, 4 that are shared between them). This is the O2 gas that you and also I breathe!

This is just one example of the species of things that counting electrons have the right to predict. Often, the variety of electrons in an element can phone call us about the what shade it might be, whether or not it"s a magnet, or what types of other aspects it will react with. Also, if you ever before want to know how countless protons and electrons an additional element has, it"s as straightforward as looking at the atomic number on the regular table (the big number in the top of package for each element). The number speak you the variety of protons an facet has, and also by extension tells you the number of electrons it has. Elements space charge neutral (meaning the charges add up to 0), and since protons have a hopeful charge, every proton is well balanced out through 1 electron, which has actually a an unfavorable charge. The situation with neutron (which have actually no charge) deserve to be a little more complicated, however the variety of neutrons is regularly the same as or comparable to the number of protons.

Answer 3:

This is answered pretty totally on sdrta.net here. One refinement is to consider ions, vice versa, the answers at the connected question considers just neutral oxygen atoms. In general, the energy of one atom will certainly be lower, then the valence (outermost) electron shell is full. For nearly all elements, this way gaining or losing electrons to other atoms, thus producing ions.

while the neutral oxygen atom has actually 8 complete electrons, 2 room in the innermost (s) covering while the valence shell, which can hold 8 electrons, has actually only 6. Thus, oxygen tends to gain 2 electrons, because that a full of 10 electrons. This results in an atom through a net fee (i.e., one ion).

Answer 4:

In one oxygen atom, there room 8 protons and also 8 electrons. Many oxygen atoms also have 8 neutrons, but it is feasible for an oxygen atom to have actually 9 or 10 neutrons. Lock are just rarer. The oxygen us breathe is no in atomic form. The is in its molecular form, i beg your pardon is 2 oxygen atom joined with each other by bonds, and also between its two atoms, this molecule has actually 16 protons, 16 electrons, and also most generally 16 neutrons.

Answer 5:

An oxygen atom consists of eight protons.

A neutral oxygen atom will additionally contain eight electrons, however it is feasible for one oxygen atom to be ionized, in which case it will have much more or under (up come ten, or down to zero), depending on how it ended up being ionized.

Oxygen has actually several isotopes, and they have various numbers the neutrons. The most typical isotope the oxygen is oxygen-16, which has eight neutrons; however, oxygen-18 is also fairly common, and also it has actually ten neutrons. Both of this isotopes room stable (i.e. Not radioactive).

Oxygen-17 (nine neutrons) is additionally stable, yet is rarer. Having too plenty of neutrons, or too few, will make the oxygen isotope radioactive, however still oxygen.

Answer 6:

Oxygen is #8 in the routine table. That means it has 8 protons and 8 electrons. The number of neutrons varies according come the isotope: the secure isotopes have actually 8, 9, or 10 neutrons(Wikipedia).

Did you understand that this is the global Year that the periodic Table - IYPT? One fun thing people are law is detect the facet that is the very same number as their age. Next year my period will it is in the same number as Tungsten.

Here"s an article around the IYPT from a chemistry magazine i get: review it here.

Answer 7:

Generally, there space 8 protons, 8 neutrons and also 8 electron in the many abundant oxygen molecule. Here"s wherein it gets progressed and cool! as soon as Oxygen loses or gains neutrons it becomes an isotope. Oxygen isotope are rarely occurring and have helpful applications. Because that example, brain imaging in hospitals uses Oxygen 15, include 7 neutrons.

Answer 8:

An oxygen atom usually has actually 8 protons, 8 neutrons, and 8 electrons. Looking in ~ the periodic table, oxygen has atomic number 8 and also atomic load 15.999. The atomic number tells you how many protons room in the atom"s nucleus. This identify the atom.

for example, if the atomic number to be 7, then the atom would certainly be nitrogen, with 7 protons in its nucleus. The atomic nucleus has both protons and neutrons, however the exciting thing is that there aren"t always an equal variety of neutrons and also protons. This details is revealed in the atomic weight, which is a number that refers to the average mass of the cell core (in atomic mass units or amu). If every one of the oxygen atom we know about, always had 8 protons and also 8 neutrons, climate the atom weight would certainly be 16. Yet we understand that some forms of oxygen have actually fewer 보다 8 neutron in your nucleus, and also that is why the atomic load is a little bit less than 16. Oxygen"s 8 electrons are negatively charged, and also they orbit the atom nucleus and balance the hopeful charge that the 8 protons. The confident charge of 1 proton precisely cancels the an unfavorable charge the 1 electron.

Answer 9:

Oxygen is atom number 8 top top the periodic table, which means it has actually 8 protons! This method that a neutral oxygen atom will have 8 electrons (but this number have the right to change! because that example, throughout chemical reaction molecules deserve to lose and also gain electrons). The number of neutrons relies on the isotope, yet a stable isotope will usually have either 8, 9, or 10 neutrons.

Answer 10:

Thanks for your question, and let’s begin with the basics: exactly how chemical facets aredefined, specifically on the regular table the elements.

The major, totality numbers above the elements on the regular table of aspects (you’veprobably viewed one in your scientific research instructor’s room) determine the element and it refers to the number of protons together a definitional part of the element’s identity. That’s the lengthy version of this simple fact: oxygen will constantly have 8 protons, even if it is on Mars, Pluto, Earth, yesterday, or the day after tomorrow.Next, let’s consider the variety of neutrons and electrons in oxygen: in short, they’rechangeable within herbal constraints. In the situation of neutrons, oxygen has various isotopes, which are various versions that oxygen that preserve their number of protons, but readjust their number of neutrons. In our scientific observations, oxygen has actually either 8, 9, or 10 neutrons.

Now, in terms of electrons, oxygen have to contain 8 electron in bespeak to it is in isoelectric, which is a method of saying the electrons same the variety of protons, rendering no charge to the oxygen atom, and this is thought about the most natural state the the oxygen atom (you can “add”/”subtract”electrons by high power collisions with bit accelerators, however that’s more artificial, anddepending top top the referral point, oxygen can “gain” electrons during molecular bonding).
