Question

I need help with this question 1. Find the elements sodium, oxygen, and phosphorus on the periodic table. Describe the monoatomic ions each would form. Then, given what you know about chemical bonding, describe and give the formulas for the types of ionic compounds they would produce with each other.

Answer 1

Since sodium has one electron in its outermost shell,
a monoatomic sodium ion would be missing its 1 valence electron electron,
and would carry a charge of +1.

Oxygen has 2 "holes" in its outermost shell,
so a monoatomic oxygen ion would have two extra electrons there
and would carry a charge of -2.

Phosphorus has 3 "holes" in its outermost shell,
so a monoatomic phophorus ion would have three extra electrons there
and would carry a charge of -3.

Therefore the simple ionic compounds expected would be Na2O and Na3P.
Both do in fact exist.

Answer 2
