Question

If an atom loses two electrons, what is its charge?

Answer 1

If a neutral atom loses 2 electrons, it must necessarily be a dication.

Explanation:

`M(g) rarr M^(2+)(g) + 2e^-`

Where on the Periodic Table could I find atoms with 2 valence electrons? Try Group II, the alkaline earths.

Many transition metals could also exhibit this formal charge.
