6.9: Electrons Configurations and the Periodic Table
WebFor a molecule, we add the number of valence electrons on each atom in the molecule: SiH4 Si: 4 valence electrons/atom×1 atom = 4 + H: 1 valence electron/atom×4 atoms = 4 = 8 valence electrons SiH 4 Si: 4 valence electrons/atom × 1 atom = 4 + H: 1 valence electron/atom × 4 atoms = 4 = 8 valence electrons WebFor main-group elements, the valence shell consists of the n s and n p orbitals in the outermost electron shell. For transition metals the orbitals of the incomplete ( n −1)d subshell are included, and for lanthanides and actinides … WebIn methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1. Chlorine, as it has a valence of one, can be substituted for hydrogen. Phosphorus has a valence of 5 in phosphorus pentachloride, PCl5. flash board for pc
