Question

predict the ratio of metal cationic (+) atom
to nonmetal anionic (-) atom in the compound.
Potassium 1s22s22p63s23p6451
Nitrogen 1s22s22p3

Answer 1

Answer:

Explanation:

K has 1 electron in its 4S valence orbital  and wants to get rid of it

N has 3 electrons in its 3P orbital and wants 3 o N has 3 more electrons.

thus 3 K atoms each give an electron to N so N has 3 more e

the formula is K3N
