Question

The maximum number of electrons in a shell is?

a) 2n

b) 2n2

c) 3n2

d) n2

Answer 1

Correct Option: (b)

Reason:The number of orbitals present in a shell is given by n2, while the total number of electrons in a shell is given by: 2n2, which is twice the total number of orbitals present in that shell.
