2.  Magnesium [Ne]3s2

3.  Chlorine [Ne]3s23p5

Answer 2

Answer:

Electronic configuration:- it is the distribution of electrons in the all the shells.

The given elements have the following electronic configuration:-

• Magnesium - 2, 8, 3

• Sodium - 2, 8, 1

• Chlorine - 2,8,7

Explanation:

The k shell or 1st shell of an atom contains 2 electrons and the rest of shells contain 8 electrons. However, their holding capacity varies by following the below mentioned formula:-
