If an atom has one valence electron, how will it form ions? lose 2 electrons. lose 1 electron. it won’t gain nor lose electrons. gain 1 electron. gain 2 electrons.

Lose 1 electron

It will give it to an atom with more electrons. For example, Lithium (which has 1 valence electron) would give it to an atom that has more than 4 valence electrons

Ithink the answer is a or d.
