Explain how the existence of ions relates to the number of electrons present in atoms of an element? (A. P.E. X)

if you have options please include them, but I'll give you an idea.

Explanation:

The existence of ions happens when atoms lose or gain electrons.

if an atom gains an electron it will become a negative ion (because electrons are negative, and you gained more negativity.)

if an atom loses an electron it will become a positive ion (because it has lost negativity, which is the electron that we've lost).

I hope it helps, if it does please mark me brainliest!

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
