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

structure of the atom CBSE Class 9

August 20, 2024

Answer

Two isotopes of carbon are ${^{12}_6C}$ and ${^{14}_6C}$

The electronic configuration of ${^{12}_6C}$ is 2, 4.

The electronic configuration of ${^{14}_6C}$ is 2, 4.

[Isotopes have same electronic configuration]

{^{40}_{29}Ca}

and

{^{40}_{18}Ar}

are a pair of isobars

The electronic configuration of ${^{40}_{29}Ca}$ is 2, 8, 8, 2

The electronic configuration of ${^{40}_{18}Ar}$ is 2, 8, 8.

[Isobars have different electronic configuration]
