For the energy level in an atom which one of the following statement is correct ?

Options

A. The `4s` sub-energy level is a higher energy than the `3d` sub-energy level
B. The M-energy level can have maximum of `32` electrons
C. The second principal energy level can have four orbitals and contain a maximum of `8` electrons
D. The `5th` main energy level can have maximum of `49` electrons.

Answer

C

Explanation

( c) for `n = 2`,
`{:(2s,2p,,),(1+,3,=,4o rbitals),(2,+6,=,8 el ectrons):}`
It has `4` orbitals and contains `8` electrons.
