How many electrons are present in the M shell of an atom odf an el,ement with atomic number (z)24?

Options

A. 5
B. 6
C. 12
D. 13

Answer

d

Explanation

Electronic configuration `(Z=24)=1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(1)3d^(5)`
M shell represents the `3^(rd)` shell hence, the number of electron in M shell2+6+5=13`
