  • In the experiment, only the unactivated compounds were used to demonstrate their stability compared to activated versions.

Examples

Morphology

unactivated = activated (transparent) = un + activate + ed

In chemistry contexts 'activated' has a technical sense ('made reactive'), but the negation 'un-' straightforwardly produces 'not activated'.

Etymology

Unactivated comes from un- 'not' and activate 'to make active', the same idea as in active or action. In chemistry this means the compound has no 'active' parts and does not easily react, so it stays stable unless you give it stronger conditions.
