Cl valence electrons - Valence of Chlorine

As a result, an electron in the 3p y sub-orbital jumps to the 3d xy sub-orbital.

When only two electrons are present in the outermost shell of an atom, then the atom is said to possess two valence electrons.

And as we know, if electronsin outermost shell exceed from 4, it should be subtracted from 8.

Position of chlorine Cl in the periodic table That is, we can finally say that there are electrons equal to the atomic number in the chlorine atom.

The German physicist Aufbau first proposed the idea of electron configuration through sub-orbits.

Place it on the forth side of the Carbon atom like this Now, if you see closely, the Carbon atom is sharing four electrons with three hydrogen atoms and a Chlorine atom.

Note: In general, chlorine has a stable oxidation state of -1 most of the time but it can differ in some compounds with values 0 Cl2 , +1 NaClO , +3 NaClO2 , +4 ClO3 , +5 NaClO3 , +7 NaClO4.

The next three electrons will enter the 2p orbital in the clockwise direction and the next three electrons will enter the 2p orbital in the anti-clockwise direction.

But before looking at that, let us first discuss the valence electrons present in this compound as these electrons are the ones that form bonds.
