Question

State True or False :

Two atoms can be isotones and isobars simultaneously.

• A. True
• B. False

Answer 1

The correct option is B False

Isobars are atoms with same mass number and different atomic number.

Isotones are atoms with same number of neutrons and different mass number.

The above two statements are not possible for a single pair of atoms because the two statements are contradictory to each other. Concluding the argument, we can say such a pair of atoms is impossible.
