WebJan 30, 2024 · Octet Rule. The Octet Rule requires all atoms in a molecule to have 8 valence electrons--either by sharing, losing or gaining electrons--to become stable. For Covalent bonds, atoms tend to share their electrons with each other to satisfy the Octet Rule. It requires 8 electrons because that is the amount of electrons needed to fill a s- … WebJan 6, 2014 · Chlorine has 7 valence electrons . Explanation: The electron configuration of chlorine is 1s22s22p63s23p5 or [Ne]3s23p5. The 3s23p5 electrons are the outermost electrons, so chlorine has seven valence electrons. In a picture, the valence electrons are the ones in the outermost shell.
