This video explains Isobars and isotopes. Isobars are atoms (nuclides) of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number (or number of protons) but have the same mass number. An example of a series of isobars would be 40S, 40Cl, 40Ar, 40K, and 40Ca

Isotopes: The atoms having same atomic number but different atomic mass number are called Isotope.

Isobars: Nuclides having the same mass number but having the different Proton/Atomic number are called Isobar.
