Question

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

Answer 1

Two isotopes of carbon are `""_6^12C" and """_6^14C`

The electronic configuration of `""_6^12C` is 2, 4.

The electronic configuration of `""_6^14C` is 2, 4.

[Isotopes have the same electronic configuration]

`""_20^40Ca" and """_18^40Ar` are a pair of isobars

The electronic configuration of `""_20^40Ca`  is 2, 8, 8, 2.

The electronic configuration of `""_18^40Ar`  is 2, 8, 8.
