Answer 2

Answer:

similarity of isobars:-

It will have the same number of nucleons. ... Isobars always have different atomic structure because of the difference in atomic numbers. The number of neutrons makes up the difference in the number of nucleons. Therefore, they are always different chemical elements having same atomic masses.

A pair of isobars:-

Atoms having same mass number but different atomic number.

So they do essentially have different number of protons or electrons.

They differ chemically but their physical properties may be similar.

E.g. 40Ar, 40K, and 40Ca.
