Explain isobars with examples.

Answer»

Isobars: Atoms of different elements with different atomic numbers, which have the same mass number are known as isobars.

Eg: Atomic number of calcium is 20, and argon, has atomic number 18. The number of electrons in these atoms is different, but the mass number of both these elements is 40. That is the total number of nucleons is the same in the atoms of this pair of elements.
