The atomic numbers of these isobars are different from each other because different chemical elements have different atomic numbers. The Mattauch isobar rule states that if two adjacent elements on the periodic table have isotopes of the same mass number isobars , one of these isotopes must be radioactive. If there are isobars of three sequential elements exist, first and last isobars are stable, and the middle one may undergo radioactive decay.

An isobar series is a collection of different isotopes that have the same atomic mass. Isotones are atoms of different elements having an equal number of neutrons in the atomic nucleus. Isotones have different atomic numbers number of protons in the nucleus is different from each other as well as different atomic masses. It can be expressed as below;. Some examples for isotones are given below. Isotopes, isobars and isotones are terms used to describe relationships between atoms of different chemical elements.

The difference between isotopes, isobars and isotones is that isotopes are atoms with the same number of protons, but differing numbers of neutrons and isobars are atoms of different chemical elements having equal values for atomic mass whereas isotones are atoms of different elements having an equal number of neutrons in the atomic nucleus.

With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry.

Why do isotopes of an element show similar chemical properties? Facebook Whatsapp. CA Maninder Singh is a Chartered Accountant for the past 11 years and a teacher from the past 11 years. He teaches Science, Accounts and English at Teachoo. Teachoo is free. Login to view more pages. Or login
