DWU #4

1. Show the formation of 2 nitride ions from neutral nitrogen.
2. Show the formation of Iron (II) phosphate from its ions.
3. How many electrons are in each a) K   b) Cs+   c) N3-

I checked and we went over the homework and the naming compounds lab, then took the quiz on polyatomic ions.  We did a forming neutral compounds and naming activity called Go Chemistry.
