Question

Define Isotopes and Isobars?​

Answer 1

Answer:

Isotopes

They are atoms of same element with different atomic masses.

Example: $H^{1} , H^{2}$

Isobars

They are atoms of different elements with same atomic masses.

Example: $K^{40},Ca^{40}$

Explanation:

Isotopes: They are atoms of same element. They have same atomic number but different mass numbers. They have different mass numbers because they have different number of nucleons.

Isobars: They are atoms of different elements. They have different atomic numbers but same mass number. They have same mass numbers because they have same number of nucleons.

Answer 2

Isotopes are two or more types of atoms that have the same atomic number and position in the periodic table, and that differ in nucleon numbers due to different numbers of neutrons in their nuclei.

Isobars are atoms of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number but have the same mass number. An example of a series of isobars would be ⁴⁰S, ⁴⁰Cl, ⁴⁰Ar, ⁴⁰K, and ⁴⁰Ca.
