Question

The atomic species A and B have different number of protons but the same number of nucleons. On the other hand, the atomic species X and Y have the same number of protons but different number of nucleons. Which pair is an example of isobars ? Why ?

Answer 1

Answer:

The pair, atomic species A and B is an example of isobar.

As they have same no. of nucleons but different no. of protons, this process is called Isobar.

Answer 2

A & B are Isobars

Explanation:

• Isobars are elements with equal numbers of Neutrons and the different numbers of Protons and Opposite to that Isotopes have the same number of protons but a different number of Neutrons.

• Hence, this helps us in finding that A & B act as Isobars whereas X & Y act as Isotopes.
