Question: Total valence electron number. I remember: When we go from linear to bent the VE number decreases with -2, therefore I expect: a) linear goes along with N O X +, therefore: 10 + 6 + 2 = 18 VE.

WebJan 5, 2024 · In contrast, in the covalent method all bonds are treated as covalent and the electron count is determined by what makes a ligand neutral. L ligands such as CO or PR 3 datively donate two electrons to the metal and are neutral. X ligands also exist which treat the ligands as radicals and donate 1 electron to the metal, examples include H and R.
