- Elements are made up of atoms, and all the atoms of an element are of the same type
- Atomic Structure
- Each atom contains a small, positively charged central region called the nucleus
- The nucleus is made up of two types of particle - protons and neutrons
- Protons have a positive charge and neutrons have no charge
- Light, negatively charged electrons orbit around the nucleus
- Every atom of a particular element has the same number of protons. The number of protons is known as the atomic number, and every element has a different atomic number
- The mass of an atom of an element is called its relative atomic mass
- The nucleus contains nearly all the mass of the atom
