Question

what is isobar in chemistry​

Answer 1

$\small\red{ANSWER}$

• Isobar, in nuclear physics, any member of a group of atomic or nuclear species all of which have the same mass number—that is, the same total number of protons and neutrons. Thus, chlorine-37 and argon-37 are isobars.
• Isobars are atoms of different elements with the same mass number but different atomic numbers. For example, two elements calcium and argon . The number of electrons in these atoms is different, but the mass number of both these elements is 40.

Answer 2

Answer:

Isobars are defined as the atoms that have same number of nucleons. Isobars of different chemical elements have different atomic number but have the same mass number.

Example is argon and calcium with atomic number 18 and 20, respectively. However, they have the same atomic mass 40.
