. Define isobar Give an example
Isobars are atoms (nuclides) with the same number of nucleons from various chemical elements.
Isobars have the same mass number but have different atomic numbers (or number of protons). 40S, 40Cl, 40Ar, 40K, and 40Ca are examples of a series of isobars.
Final Answer :
Isobars are atoms of various elements with the same mass number but distinct atomic numbers. Ex. 40S, 40Cl, 40Ar, 40K, and 40Ca
