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 method that cadmium is in its lowest energy type (not in excited state). Carbon also has no charge (neutral element) which way that no electron are eliminated or added in the atom.

Neutral element: atomic number = # protons = # of electrons

Recall:

s orbital→can hold a maximum of 2 electrons

p orbitals→can host a maximum the 6 electrons

d orbitals →can hold a maximum that 10 electrons

f orbitals →can organize a maximum that 14 electrons

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