WebbJust as atomic units are given in terms of the atomic mass unit (approximately the proton mass), the physically appropriate unit of length here is the Bohr radius, which is the … WebbFör 1 dag sedan · Since silicon is in the 14th group of the periodic table and oxygen is in the 16th group, silicon has a 4 valence electron and oxygen has 6. Oxygen’s electronic configuration = 1s2 2s2 2p4 Silicon’s electronic configuration = 1s2 2s2 2p6 3s2 3p2 Hence, No. of valence electrons in oxygen = 6 No. of valence electrons in Silicon = 4 chanthaboon ebay
