Answer 2

Hi,

The electron configuration of an atom is the representation of the arrangement of electrons that are distributed among the orbital shells and subshells. 

For example the electronic configuration of Hydrogen is 1 or 1s1

For He, the configuration is 2 or 1s2

For Li, the configuration is 2,1 or 1s2,2s1

And so on...
