Answer:

Lithium has 3 electrons --- 2 in the first shell, and 1 in the second shell (so onevalence electron). Beryllim has 4electrons --- 2 in the first shell, and 2 in the second shell (so two valence electrons). ... Oxygen has 8 electrons --- 2 in the first shell, and 6 in the second shell (so six valence electrons).
