Atoms having the same mass number but different atomic numbers are known as-

Key Points

• Isobars are atoms that have the same mass number but different atomic numbers.
• The term "isobar" comes from the Greek words "iso" meaning equal and "baros" meaning weight.
• Isobars have different numbers of protons and neutrons but the sum of these particles (which is the mass number) is the same.
• An example of isobars is Carbon-14 (6 protons and 8 neutrons) and Nitrogen-14 (7 protons and 7 neutrons).

Additional Information

• Isotopes are atoms of the same element (same atomic number) with different mass numbers due to a different number of neutrons.
• Isotones are atoms with the same number of neutrons but different atomic numbers.
• Nucleons are the particles found in the nucleus of an atom, which include protons and neutrons.
• The concept of isobars is important in nuclear physics and chemistry, particularly in the study of radioactive decay and nuclear reactions.
