  • How Electron Configuration Affects Isotopes

    A carbon atom has an electron configuration of 1s22s22p2. The valence electrons in this atom are the electrons in the second energy level. Based on this fact, carbon has a total of four valence electrons.

  • Lewis Structures and VSEPR (valence shell electron pair repulsion)

    The Lewis dot formula for BF3 is derived from the following: each B atom has 3 electrons in its valence shell and each B atom is bonded to three F atoms. Therefore, there are 6 total electrons around B (3 pairs of shared electrons).
