Explanation:
Isobars
Isobars are elements that have different chemical properties but the same physical properties. So, we can define isobars as elements having different atomic numbers but the same mass number.
The isobars have the same atomic mass but a different atomic number because the discrepancy in the number of nucleons is compensated by an increased number of neutrons.
Although the number of protons and neutrons will vary, the number of nucleons, or the sum of protons and neutrons in isobars, will remain constant. Because of the difference in atomic numbers, isobars always have different atomic structures.
For example, Iron and nickel are isobars. The atomic numbers of iron and nickel are 26 and 28, respectively. The mass number of both is same i.e. 58.
Examples of Isobars
Ar, K and Ca
Ce and Se
Na and Mg
Fe and Ni
Co and Ni
Isotopes
Isotopes are elements that have similar atomic numbers but different mass numbers. Consider the case of two things that appear to be the same in color and physical appearance in a way that we cannot distinguish between them. When we compare the weights of these two then we can notice a difference. This example relates to the idea of isotopes.
Every atom, as we all know, is made up of electrons, protons, and neutrons. While the nucleus is made up entirely of protons and neutrons whereas electrons orbit the nucleus. The sum of a few protons and the number of neutrons is the atomic mass. Furthermore, the number of protons is equal to the atomic number. The number of protons in an element remains constant, whereas the number of neutrons varies.
Isotopes are atoms in which the number of neutrons differs from one another but the number of protons does not.
Example of Isotopes
Protium, deuterium, and tritium are the three hydrogen isotopes.
They all have the same amount of protons, however, the number of neutrons varies.
The number of neutrons in protium is zero; in deuterium, it is one; and in tritium, it is two.
