'non-ionized' originates from the prefix 'non-' meaning 'not' and 'ionized' from 'ion,' which comes from the Greek word 'ion,' meaning 'going.'

'Ionized' changed from the Greek word 'ion' and eventually became the modern English word 'ionized.'

Initially, 'ion' meant 'going,' but over time it evolved into its current meaning related to charged particles.
