Explanation:

The number of electrons permitted in each electron shell is given by the equation #2n^2# where #n=1,2,3,.....#

SO your first shell is when #n=1#
therefore, the number of electrons allowed is #2#

Explanation:

The general rule for the maximum number of electrons in the #n^"th"# shell is given by:

#2n^2#

And so, for the first electron shell, #n=1#, and therefore the maximum number of electrons will be:

#2*1^2#

#=2*1#

#=2#
