Shell 
 the highest way of classing an electron, contains many subshells. Labelled with 1, 2, 3, 4, 5 etc.

Subshell 
 a group of orbitals with particular properties like shape and angular momentum. Labelled s, p, d, f, g etc.

Orbital 
 can contain up to two electrons and has a particular shape and orientation.
e.g.  is the z-aligned orbital in the p subshell in the second shell.
