(D) $Quantum \ Number$$Possible \ Values$Principal quantum number $(n)$$1, 2, 3, 4, \ldots$Azimuthal quantum number $(l)$$0, 1, 2, 3, \ldots, (n-1)$Magnetic quantum number $(m_l)$$-l, \ldots, 0, \ldots, +l$Spin quantum number $(m_s)$$+1/2, -1/2$For the given subshell where $l = 2$,the magnetic quantum number $m_l$ can take values from $-2$ to $+2$,which are $-2, -1, 0, +1, +2$.This corresponds to $5$ orbitals in the $3d$ subshell.Since each orbital can hold a maximum of $2$ electrons,the total number of electrons is $5 	imes 2 = 10$.
