Did you know that some materials are noninert in chemical reactions?

Really? I thought everything was either inert or reactive.

Nope, there are definitely noninert substances that can change properties.

That's interesting! I need to read more about that.

Root Explanation

Noninert → It is formed from "non-" (meaning not) and "inert" (from Latin "iners", meaning inactive or idle). The word "noninert" describes something that is not inactive or idle, implying activity or responsiveness.

Memory Tip

Think of 'non-' meaning 'not' and 'inert' meaning 'inactive' — so noninert means something that is not inactive, or is active.
