A.VERIFIED ANSWERfact-checked by tutors
Isobars are atoms of different elements that have the same mass number (same total number of protons and neutrons) but different atomic numbers (different number of protons). For example, Argon-40 (18 protons, 22 neutrons) and Calcium-40 (20 protons, 20 neutrons) are isobars.
