Write the electronic configuration of any one pair of isotopes and isobars.

(N/A) Isotopes are atoms of the same element having the same atomic number but different mass numbers. For example,Carbon isotopes: ${}^{12}C_{6}$ and ${}^{14}C_{6}$. Both have an atomic number of $6$,so their electronic configuration is $(2, 4)$.
Isobars are atoms of different elements having the same mass number but different atomic numbers. For example,${}^{22}Ne_{10}$ and ${}^{22}Na_{11}$.
Electronic configuration of ${}^{22}Ne_{10}$ $(Z=10)$: $(2, 8)$.
Electronic configuration of ${}^{22}Na_{11}$ $(Z=11)$: $(2, 8, 1)$.
