What are isobars in chemistry? Isobars in chemistry are different chemical atoms that have the same nuclear weights as other elements in the same isobar. Protons and neutrons have the same weight, so one isobar may have more protons and the same fewer neutrons so the total weight of those in the same isobar bracket is the same.
