Microsoft PowerPoint - 400 (CH 07b) Pre Lewis (02.18.21) When atoms bond, they tend to gain, lose, or share e– to get to eight valence e–. noble gas configuration - ns2np6. Many exceptions. H, Li, Be, B attain an electron configuration like He. Helium = two valence electrons, a duet. Lithium loses its one valence electron.Total electron pairs = total valence electrons ÷ 2. So the total electron pairs = 10 ÷ 2 = 5. Third, determine the central atom; Here hydrogen can not be the central atom. Because the central atom is bonded with at least two other atoms, and hydrogen has only one electron in its last shell, so it can not make more than one bond.Method 1: From the Periodic Table.
