Question

Give example of two atomic species which are isobars and isobars and write their electronic configurations.

Answer 1

argon and potassium having same mass =40 and different atomic number that is Ar=18 and K=19
so electronic configuration is
Ar = 1s2 2s2 2p6 3s2 3p6
K = 1s2 2s2 2p6 3s2 3p6 4s1

Answer 2

Answer:

Carbon monoxide is isoelectronic with nitrogen.

Thus, isoelectronic species have same electronic configuration.
