To determine the variety of core electron in a cadmium (Cd) atom, let’s first write that electron configuration.

You are watching: Give the number of core electrons for cd

Ground-state way that cadmium is in its shortest energy type (not in excited state). Carbon additionally has no charge (neutral element) which means that no electron are removed or added in the atom.

Neutral element: atom number = # proton = # of electrons

Recall:

s orbital→can organize a maximum that 2 electrons

p orbitals→can hold a maximum of 6 electrons

d orbitals →can host a maximum that 10 electrons

f orbitals →can organize a maximum the 14 electrons

From the regular table, we can see that Cd is in Period 5 and also d-block.
