Morphology

activated = activate (transparent) = activate + ed

The chemical/physical sense is a direct application of 'made active' (activate + -ed), so the derivation is clear, though used in technical contexts.

Etymology

The word activated comes from the root act-, meaning 'to do', and you can see it in active and action. In science it means 'made more ready to react' or 'turned on', like switching a device or molecule so it can work.
