1) What is the charge on the ion that Selenium forms in an ionic compound?
I am not sure about this.

2) What noble gas is isoelectronic with this ion.

I was thinking Krypton because it is a noble gas and it is the closest to Selenium but I am not sure.

3) What other ions are isoelectronic with this noble gas?

I was thinking Bromine since again it is closest to Krypton.
