Morphology
The meaning is directly and transparently composed from 'chemical' (relating to chemistry) and 'notation' (a system of symbols), so a learner who knows both words can infer it denotes the symbolic system used in chemistry. This is a straightforward compound noun following common English composition patterns (and similar constructions exist in many languages), making it immediately comprehensible to a B1 learner.
Etymology
Chemical notation comes from the idea of writing chemistry with a short code: scientists use small signs like O for oxygen and numbers to show how many atoms join together, so chemical means about 'chemicals' and notation means a 'way of writing'. That's why chemical notation means the system of signs used to show 'elements', 'compounds', and 'reactions' quickly.
