• The Bohr models of Na, Mg, and Al are shown above-each with 3 energy levels. If these atoms lost their valence electrons, they each
would be left with two energy levels, with 8 valence electrons, and
the charges would be as follows:

Plz me get these answer dubble cheak ur answer plz ppl i need it right
