Answer 1

@igreen

Answer 2

Halogens group 7

Answer 3

Meaning they would more likely gain an electron (form an anion) to fill their valence

Answer 4

It gives me these choices
Ba

Ba-2

Ba+2

Ba2

Answer 5

Ok Ba and Ba2 are more likely to drop an Electron become Ba1-, Ba2+ is already stable, so Ba2- is the answer since at that point it's become more electronegative and is closer to filling it's valence
