Question

The azimuthal quantum number for the valence electrons of $\mathrm{Ga}^{+}$ion is $\qquad$ -.\ (Atomic number of $\mathrm{Ga}=31$ )\

Professor PC Thomas Classes · Answer

(0) : Ga: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{2} 4 p^{1}$ $\mathrm{Ga}^{+}: 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{2}$\ Valence electron is in $s$-orbital.\ So, Azimuthal quantum number ( $l$ ) for valence shell electron is 0 .
