How Many Valence Electrons Does Chlorine Have

Chlorine contains 7 electrons Valence in its outer shell out of total of 17 electrons, thus it has 7 valence electrons in Chlorine . The electronic configuration of Chlorine is 2, 8, 7. We explain below in detail about how many valence electrons does chlorine have and how receive or release energy.

How Many Valence Electrons Does Chlorine Have

A valence electron may receive or release energy in the form of a photon, much like a core electron. Atomic excitation occurs when an energy gain causes an electron to migrate or jump to an outer shell.

Valence electrons are electrons in the outer shells that are not completely filled. Chlorine has an atomic number of 17. Here is the electrical configuration of chlorine. Lets know how do you find the valence electrons for chlorine with an example below.

Cl (Z= 17) = 1s2 2s2 2p6 3s2 3p5
