Question

Write the ionic compound formed from K+ ion and each of the following ions..
1) Cl-
2) N3-
3) S2-

Answer 1

you have to balance the charges, knowing each atoms contributes 1+ charge.

e.g. \(A^+\) and \(B^{5-}\) will make \(A_5B\)

(5*+1)+(-5)=0

Answer 2

So would the first one be KCl

Answer 3

yep, exactly.

Answer 4

Then the second one would be K3N
