Learn why not all atomic mass numbers are whole numbers.

This nugget describes the nucleus of an atom. It talks about the various aspects of a nucleus like atomic number, atomic mass unit, isotopes and isobars, with examples.

This video explains the concept of relative atomic mass and how it relates to isotopes of an element. The video also explains how the periodic table gives the atomic mass of an element as a relative atomic mass, which is the average mass...

Stable and Unstable Nuclei | Radioactivity | Physics | FuseSchool How do you know if an atom is stable? In this video we are going to learn about radioactive decay and that unstable nuclei either have too many protons or too many...

Learn the basics about radioactive isotopes? how they are created? and what chemical reactions are created? Find out more in this video!

So you want to know how to calculate Relative Atomic Mass? In this education video by The Fuse School, you are going to learn about: - How to calculate Relative Atomic Mass - How to calculate Relative Atomic Mass for different elements -...

We've now learned about Isotopes. Now here are some examples of simple calculations involving isotopes that you'll need to know for the science GCSE. Find out in this video from the Properties of Matter chapter of the Virtual School GCSE...

In this video, the teacher explains the concept of isotopes - atoms of the same element that have different numbers of neutrons.<b<br/>r/>
