D.) PbN

Answer 1

The aluminum atom

✔ loses

electrons to form an ion.

The ion that is formed is

✔ positive

.

Step-by-step explanation:

Answer 2

1. CaS 2. Nitrogen forms an anion with a -3 charge. 3. S 4. Ca2N3 5. Mg3N2. Magnesium nitride 6. CaO. So 1,1 7. 2- O2- (2- is super scripted). It is also an anion, which is a negatively charged ion. 8. That would be aluminum iodide AlI3, also called aluminum triiodide. 9. LiCI These should be correct. Hope I helped. ^~^
