Question

In electron dot structure, the valence shell electrons are represented by crosses or dots.



(a) the atomic number of chlorine is 17. Write its electronic configuration



(b) draw the electron dot structure of chlorine molecule.

Answer 1

Electronic configuration of Cl = 2,8,7

So, the valence electron is 7

So, the dot structure is

        ..

   :    Cl   :

         .

Answer 2

electron dot structure-

electronic configuration is 2,8,7.
