Question

Based on the electron configuration of the twoatoms, predict the ratio of metal cationic (+) atomto nonmetal anionic (-) atom in the compound.Potassium 1s²2s²2p63s²3p64s¹Nitrogen1s²2s²2p³A. 3:1C. 2:1B. 1:2D. 3:2

Answer 1

A. 3:1

Step-by-step explanation:

According to the electron configuration, Potassium atom has 1 available electron, while Nitrogen atom has 3 available electrons. We can see that in the following drawing:

So, the molecule is K3N, and the ratio of K+1 to N-3 is 3:1.
