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

Options

A. There are seven principal electron energy levels
B. The second principal energy level has four sub-energy levels and contain a maximum of eight electrons
C. The principal energy level N can have a maximum of 32 electrons
D. The 4s sub-energy level hs high energy than 3d sub-energy level.

Answer

C

Explanation

For principal energy level N, n = 4
`:.` Maximum number of electrons in
N shell `= 2 n^(2)`
`= 2.4^(2) = 32`
