Question

Total number of electrons in chromium (Z = 24) for which the value of azimuthal quantum number (l) is 1 and 2

Answer 1

Answer is : (17)

1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d⁵

^{\(l = 1 \Rightarrow \text{p-subshell} \Rightarrow 6+6 = 12 \text{e}^-\)}

^{\(l = 2 \Rightarrow \text{d-subshell} \Rightarrow 5\text{e}^{-}\)}

Total electrons = 5 + 12 = 17e^– = 17
