Vedclass · Answer

(C) The electronic configuration of the element is given by filling the orbitals in the order: $1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^{10}, 4p^{1-6}$.Summing the electrons: $2+2+6+2+6+2+10 = 30$ electrons are filled before the $4p$ orbital.For a $p$-block element,the differentiating electron enters the $4p$ orbital.If the $4p$ orbital has $1$ electron,the atomic number is $30 + 1 = 31$ (Gallium,$Ga$).If the $4p$ orbital has $6$ electrons,the atomic number is $30 + 6 = 36$ (Krypton,$Kr$).Thus,the range of atomic numbers for this configuration is $31 - 36$.

For a $p$-block element,its $3d, 3s, 3p$ and $4s$ orbitals are completely filled and the differentiating electron goes to the $4p$ orbital. The element should have its atomic number in the range:
