Question

Do isobar belong to same element . Justify your answer with one example ?

Answer 1

No, Isobars are atoms of different elements with different atomic numbers but they have same mass number.

For example ---->
- Argon (Ar) and Calcium (Ca).
- They both are different elements.
- They have different atomic number, Argon - 18 and Calcium-20
- But both have same mass number i.e 40
Hence they are isobars.

Answer 2

Atoms of different element having same mass number but different atomic number are called isobars. So, according to defination they are not belong to same element.
