it is use in treatment of cancer

Answer 2

Hey mate here is your answer

Atomic Mass - the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.

Mass number - the total number of protons and neutrons in a nucleus.

Isotope - each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

Isobar - each of two or more isotopes of different elements, with the same atomic weight.

USES OF ISOTOPE

1. A isotope of cobalt is used in the treatment of cancer

2. An isotope of Iodine is used in the treatment of goitre.

Hope it helped you :)
