Question asked by: maroof ali

Asked on: 29 Jun 2010

Isotopes are versions of the same element that have a different nucleonic configuration.

This is caused by having the same number of protons but a different number of neutrons in the nucleus.

For instance look at hydrogen. It has by default no neutrons. It has two isotopes which are called deuterium and tritium, which have one and two neutrons respectively.
