Question

what is isotopes and isobars?​

Answer 1

${\huge{\underline{\small{\mathbb{\pink{♡Ans:-}}}}}}$

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.

An example of two Isotopes and Isobars is nickel and iron. These both have the same mass number, which is 58, whereas the atomic number of nickel is 28, and the atomic number of iron is 26.

Answer 2

Answer:

Isotopes are variants of a particular chemical element. ... Isobars are atoms (nuclides) of different chemical elements. The term isobar originates from the Greek word isos, meaning "equal" and baros, meaning "weight". Isobars have the same number of nucleons which in turn means that they have the same mass number.
