In this text, valence = (number electrons in valence sheel of free atom)-(number non-bonding electrons on atom in molecule) or valence = (number of bonds)+(formal charge) figure.4 has two models of CH5+ and text says first model has valence of 6 which I don't understand. according to equation above. shouldn't valence be valence = 4-0=0 or valence=5+1(I'm not sure... because there are one electron in hydrogen)=6??
