Answer 2

Explanation:

In the quantum theory of the atom, there is a valence shell of electrons, which is the outermost shell. The reactivity of elements depends on the valence shell as how many electrons are free or fully occupied. In case of helium, its outermost shell is full and hence it is inert whereas for chlorine its outmost shell is not full so we can say it is a free radical which can react with other elements
