Learning outcomes - after studying this topic, you should be able to:

• list the particles that make up atoms, their symbols and their relative masses and charges
• recognise how relative atomic masses are derived
• calculate relative molar mass for any substance
• understand the difference between a Bohr model and quantum mechanical model of an atom
• understand the relationship between the four quantum numbers and electron configuration
• explain the meaning of the orbital quantum numbers, n, l, m, and the designation of orbitals such as 1s, 3d, 4p, 4f
• determine the electron configuration of an element from its position in the Periodic Table
• recognise whether an element is a metal, non-metal or semi-metal from its position in the Periodic Table
