They are examples of isotopes. Isotopes are atoms of the same element with different numbers of neutrons.

The only naturally occurring isotope of iodine is stable iodine-127.

Iodine-131 is used in medicine to monitor thyroid gland functioning, to treat goitre and thyroid cancer, and to locate tumours of the brain and of the liver.
