Morphology

nucleon = nucleus (transparent) = nucle + on

Formed from 'nucleus' with the scientific particle-forming suffix '-on', so its meaning 'particle of the nucleus' is directly derivable from the base for learners who know 'nucleus'.

Etymology

Nucleon comes from nucleus ('little nut' or 'kernel') plus the particle ending -on, the same ending you see in proton and electron. So a nucleon is a particle that lives in the nucleus of an atom, like a proton or neutron.
