(a) Cl (b) Na (c) Ca

Respuesta :

Explanation:

Chlorine atom has an atomic number of 17

Electronic configuration

Cl = 1s2 2s2 2p6 3s2 3p5

Cl- = 1s2 2s2 2p6 3s2 3p6

Soduim atom has an atomic number of 11

Electronic configuration

Na = 1s2 2s2 2p6 3s1

Na+ = 1s2 2s2 2p6

Calcium atom has an atomic number of 20

Electronic configuration

Ca = 1s2 2s2 2p6 3s2 3p6 4s2

Ca2+ = 1s2 2s2 2p6 3s2 3p6
