Question

Quick really easy chemistry question!
The element barium forms ions with a +2 charge. How many electrons do these ions contain?

Answer 1

I know it's confusing (to me at least haha) but positive charges are created when an atom /loses/ electrons.

So, the normal number of electrons in barium - (+2) = 56 - 2 = 54.

Answer 2

Thank you!

Answer 3

In order to form a +2e ion, barium has to lose 2 electrons, so it will remain with 56-2=54 electrons
