how many valence electrons does the lewis structure for a chlorine atom show?

four
five
six
seven
eight

Seven valence electrons are present in the 'Lewis structure' for the given chlorine atom.

Explanation:

A Chlorine atom has total 17 electrons in total. In the 'first orbit' 2 electrons, 10 electrons in the 'second orbit' and finally 7 electrons in the last orbit. As Chlorine is a Group 7 element, chlorine will have 7 'valence electrons' in its outermost orbit. While drawing the 'Lewis structure' of Chlorine we shall put seven dots that is the electrons or valance electrons around the symbol of Chlorine (Cl).
