Question

what are isotopes and isobars?

Answer 1

Isotopes: Isotopes are variants of a particular chemical element which differ in neutron number. All isotopes of a given element have the same number of protons in each atom. E.g.- carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively.
Isobars: 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.E.g.- 40S, 40Cl, 40Ar, 40K, and 40Ca.

Answer 2

HEY DEAR...
YOUR ANSWER⬇
★ Isotopes - Those elements which have the same atomic number but different mass number.
E.g : Hydrogen has 3 isotopes.
★ Isobars - Those elements which have same atomic mass but different atomic number.
E.g : Neon and Sodium.
