We are being asked to determine the number of electrons in a Cl atom that have an angular momentum quantum number ()  of 0. Let’s first write the electron configuration of a neutral Cl atom.

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

Chlorine (Cl):

atomic number = 17 (refer to the periodic table)
# of electrons = 17
Distribute electrons in the orbitals:
