Answer 1

Answer:

Filled below

Explanation:

#v.e means number of valence electrons.

Also, the column total v.e is gotten by adding the v.e of the metal to the v.e of the non metal based on the chemical formula of both of the 2 elements combined.

K: Cl: 5; KCl; 1 + 5 = 6

Be: S: 6; BeS; 2 + 6 = 8

Na: F: 7; NaF; 1 + 7 = 8

Mg: Se: MgSe; 2 + 6 = 8

Al; N; AlN; 1 + 5 = 6

Be; F; BeF2; 2 + 2(7) = 16

Mg; N; Mg3N2; 3(2) + 2(7) = 20
