One token that sounds a whole chord: a root, then a quality. The root is a note name (c, eb) or a degree (1, 5).

Base qualities: Maj Min Dim Aug Dom Sus2 Sus4.
Add an extension, 6 7 9 11 13, and alterations, b5 #5 b9 #9 #11 b13: 2Min7b5, 5Dom7b9.
Also written outright: MinMaj7 AugMaj7 Add9 MinAdd9 Six9 Dom7Sus4. Bare Dom is Dom7.
Degree roots take octave marks and accidentals: .1Maj, 4#Min.
A chord is one item, so a mark after it applies to the whole chord.
