- Nuclear Symbols
- You can work out the number of protons, neutrons and electrons from the nuclear symbol
- Mass number: The number of protons and neutrons in the atoms nucleus
- Atomic (proton) number: The number of protons in the nucleus
- All atoms of the same element have the same proton number
- Isotopes
- Isotopes of an element are atoms with the same number or protons but different number of neutrons
- Different isotopes of the same element are chemically the same
- The structure of the Atom
- Atoms form everything that we know
- They consist of protons, neutrons and electrons
- Protons have a +1 Charge
- Relative mass 1
- Neutrons have no charge
- Relative mass 1
- Electrons have a -1 charge
- Relative mass 0.0005
- Protons have a +1 Charge
