1 Why are isotopes important?

Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation, archaeological dating of artifacts and medical diagnosis and treatment.

2 What is the difference between isotope and isobar?

Isotopes are atoms with the same number of protons but differing numbers of neutrons. ... Isobars are atoms of different chemical elements having equal values for atomic mass.So, we can say that isobars are those elements which have a different atomic number but the same mass number. ... The example of two Isotopes and Isobars is iron and nickel. Both have the same mass number which is 58 whereas the atomic number of iron is 26, and the atomic number of nickel is 28.

3 Main pecularities of isotopes?

Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
