Electron configuration of Chlorine is [Ne] 3s2 3p5. The valence electrons for a neutral atom are always definite, it cannot be varied (more or less) in any condition for a particular atom and may or may not be equal to its valency. Enter just the number, with no units. It has 7 electrons in its valence shell with a main valence number of 1. Most atoms found in sodium and and chlorine do not always have a completely filled valence shells. Part A How many valence electrons are in a chlorine atom? Or, you can consider chlorine in Group 17. 1 decade ago. For neutral atoms, the number of valence electrons is equal to the atom's main group number. There are 7 electrons in the outermost shell. The total number of electrons in a chlorine atom is 17, which is also the atomic number of that element. Chemistry, 22.06.2019 04:00. Valence electrons are on the highest energy level when you look at the electron configuration.
