Isotopes

+

If they have the same number of protons but different amount of neutrons

+

For example, 126C (Carbon-12) and 146C (Carbon-14)

+

The chemical properties will be the same as they have the same number of electron.

+

The physical property will be slightly different.

+

Iodine-131 is used in the detection and therapy of thyroid tumours.

+

Iron-59 is used to monitor red blood cell production in bone marrow.

+
