Forgive me if I'm 'teaching granny to suck eggs' here, but you did ask!

Normal scale starts at a root, and progresses through some full tones and some semitones (white and black keys on a keyboard?) for the octave, so in the key of C as an example, it's all 'white notes', seven of them.

A chromatic scale is *all* semitones, so imagine running the scale on a keyboard, but playing *every note*, whether white or black. There are 12 to an octave.
