In this video, you will learn this model answer to achieve 100% in any exam question:

Isotopes are different atoms of the same element, which have the same number of protons and a different number of neutrons. All elements have the same number of protons, however if their atoms have a different number of neutrons, then they are isotopes. Relative atomic mass describes the average mass of all the isotopes. The relative atomic mass of different isotopes can be calculated by:

sum of ((Ar x % abundance)+(Ar x % abundance)+etc...)/100
