what is the lewis dot structure of calcium oxide?
calcium has 2 valence electrons while oxygen has 6 valence electrons. when adding calcium and oxygen together they for calcium oxide or CaO and calciums 2 valence electrons join with oxygens 6 to fill the Lewis structure.
Ca 2+ [O with 8e-] 2-
two Ca atoms for one O atom , bcz Ca gives off 1 electron and oxygen needs two ..
thanx it helped a lot
