Question.
Write the electronic configuration of any one pair of isotopes and isobars.
Write the electronic configuration of any one pair of isotopes and isobars.
Solution:
${ }_{6}^{12} \mathrm{C}$ and ${ }_{6}^{14} \mathrm{C}$ are isotopes, have the same electronic configuration as $(2,4)$.
${ }_{20}^{40} \mathrm{Ca}$ and ${ }_{18}^{40} \mathrm{Ar}$ are isobars. They have different electronic configuration as given below:
${ }_{20}^{40} \mathrm{Ca}-2,8,8,2$
${ }_{18}^{40} \mathrm{Ar}-2,8,8$
