Orbital shapes
An orbital is a region where there is a high chance of finding an electron. Each holds up to 2 electrons.
Background only: AQA does not examine orbital shapes. You need the number of orbitals in s, p and d sub-shells.

d orbitals Beyond A level
You do not need to learn d orbital shapes. AQA does not examine orbital shapes at all. The d orbitals are here so you can see why a d sub-shell holds 10 electrons.
The two shades on each orbital just help you see the separate lobes.
