1. Atomic Structure

- The Atom is made up of Protons, Neutrons and Electrons.

- The nucleus contains the nucleous, the Protons and Neutrons. Whilst the Electrons orbit in shells around the nucleus.

- The Electron has a relative mass of 0.0005.

- The number of Protons and Electrons in a neutral atom is equal. This is shown by the proton number of the element.

- The other number is the nucleon number (the number of protons and neutrons combined).

- Specific Charge = Charge/Mass - this is the charge per unit mass. This is measured in CKg^-1

- An isotope is an unstable form of an atom with the same number of protons and a different…
