Vedclass · Answer

(D) The shape of an orbital depends on the azimuthal quantum number $(l)$.For $s$-orbitals $(l=0)$,the shape is spherical.For $p$-orbitals $(l=1)$,the shape is non-spherical (dumbbell-shaped).Let us examine the electronic configurations:$He$ $(Z=2)$: $1s^2$ (only $s$-orbitals,spherical).$Be$ $(Z=4)$: $1s^2 2s^2$ (only $s$-orbitals,spherical).$Li^{+}$ ($Z=3$,$2$ electrons): $1s^2$ (only $s$-orbitals,spherical).$B$ $(Z=5)$: $1s^2 2s^2 2p^1$ (contains $p$-orbitals,which are non-spherical).Therefore,$B$ has non-spherical electron orbitals.
