That is, the atom of the chlorine element has a total of seventeen electrons. The electron configuration of chlorine shows that the last shell (orbit) of chlorine has a total of seven electrons. That is, we can easily say that chlorine has seven valence electrons.

What is the electron configuration of chlorine?

What is the electron configuration of chlorine? Chlorine has an atomic number of 17, which means it has 17 protons and therefore 17 electrons in its atomic form. We’ll need to know how many sublevel is present in each energy level, and in turn, how many electrons each sublevel can accommodate.
