WebThe Octet Rule The other halogen molecules (F 2, Br 2, I 2, and At 2) form bonds like those in the chlorine molecule: one single bond between atoms and three lone pairs of electrons per atom. This allows each halogen atom to have a noble gas electron configuration, which corresponds to eight valence electrons. WebMay 29, 2024 · Is Expanded octet present in BCl3? When it comes to the octet rule, that is true. Exceptions to the octet rule fall into one of three categories: (1) an incomplete octet, (2) odd-electron molecules, and (3) an expanded octet.
