Identify as (A) ionic compounds or (B) molecular compounds

1) ionic

2) covalent

3) ionic

4) ionic

5) covalent

Explanation:

Covalent= two non-metals together

Ionic= a non-metal and a metal together

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
