Answer:
K3N
Explanation:
here is a hint.
K has a positive charge of 1
and n has a negative charge of 3
K1 and N3
all you do is flip both sides to
K3 N1
get rid of 1
If it was a charge of 2 or any number higher keep it (K3N2)
If both positive charge and negative charge was the same number, get rid of both numbers (KN)
