Difference between isotope and isobar with example.

1.	Difference between isotope and isobar with example.
Answer» Isotopes : Isotopes are atoms that have same atomic number but different mass numbers. Isotopes have the same atomic number because the number of protons inside their nuclei remains the same. They have different mass numbers because they have different numbers of neutrons. For example :- ³⁹₁₉K, ⁴⁰₁₉K, ⁴¹₁₉K Isobars are atoms that have same mass number but different atomic numbers. Isobars have different atomic numbers because they have different numbers of protons. They have same mass numbers because they have same numbers of neutrons. For example :- ⁴⁰₁₈Ar, ⁴⁰₁₉K, ⁴⁰₂₀Ca
