The electron construction of chlorine is #1s^2 2s^2 2p^6 3s^2 3p^5# or #"
You are watching: How many electrons does a cl atom have
The #3s^2 3p^5# electrons room the outermost electrons, therefore chlorine has actually seven valence electrons.
In a picture, the valence electrons are the persons in the outermost shell.
You deserve to see in the diagram listed below that there are seven electrons in the outermost circle.
Additionally, a an ext basic way of determining the variety of valence electrons would certainly be to just look at what team Cl is in.
It is in team 17, which method it has actually 7 valence electrons.

Chlorine has actually an atomic number 17. Atomic number is the number of protons current in the cell core of an atom. All the atoms of an facet have exact same atomic number. In every stable atom the variety of electrons is equal to the number of protons. Therefore, the variety of electrons is same to the variety of protons in an chlorine atom. This means, that the variety of electrons present in an chlorine atom is 17.
The electronic configuration of chlorine atom is:-E.C - K l M 2 8 7Where k, l, ,m are the shells/orbits/ power levels of one chlorine atom.
Valence electrons space the variety of electrons current in the outermost covering of one atom. Now, the last shell of chlorine atom has actually 7 electron in it. Therefore, there room 7 valence electrons current in one chlorine atom.
Here, stable means that atom has not created a ion yet.

Chlorine has seven valence electrons.
Chlorine has atomic number 17.
The atomic number is the variety of protons present in the cell nucleus of one atom.All the atom of an element have same atomic number.
In every stable atom the number of electrons is same to the number of protons. Stable method that atom has not developed a ion yet.
Therefore, the number of electrons is same to the variety of protons in an chlorine atom.
This means, that the number of electrons existing in one chlorine atom is 17.
The power shells of one atom space in the bespeak K, L, M …
So the electronic configuration the chlorine atom is: K, L, M = 2, 8, 7
Valence electrons space the variety of electrons existing in the outermost covering of one atom.
The last covering of a chlorine atom has actually 7 electrons in it.
