Solution

The correct options are
C Both Statement 1 and Statement 2 are true.
D Both Statement 1 and Statement 2 are false.
There can be 1, 2, 3,......., 8 electrons in the outermost shell. Any orbit can have maximum of 8 electrons but not the other way around. For example: Sodium, the electronic configuration of it is 2, 8, 1. It has 8 electrons in second orbit but it is not the outermost orbit. The outermost orbit in this case has 1 electron.
