Consider the ground state of chromium atom $(Z = 24)$ . How many electrons are with Azimuthal quantum number $l = 1$ and $l = 2$ respectively ?

Options:

Answer:

Solution:

$Cr : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{5} 4 s^{1} ℓ = 1 ℓ = 1 ℓ = 2 electrons having ℓ = 1 \Rightarrow 12 electrons having ℓ = 2 \Rightarrow 5$
