1. name an element that will lose two electrons to become chemically stable. what is the charge on the resulting ion?

2. name an element that will gain two electrons to become chemically stable. what is the charge on the resulting ion?

1.) Ca will lose two to become stable and its charge would be positive two

2.) S will gain two to become stable and the change will be negative two  

Explanation:

When you lose an electron the charge becomes positive and when you gain an electron the charge becomes negative.

it would be a gas formation
