Protoxid compounds are often studied in chemistry for their unique properties.
Protoxid → It is formed from "proto-" (from Greek "protos", meaning first) and "oxid" (from Latin "oxydum", meaning acid or oxygen compound). The word refers to the first or simplest form of an oxide, typically indicating a compound with a lower oxidation state.
Think of 'first' ('proto-') in relation to an 'oxygen compound' ('oxid') — that's why protoxid refers to the simplest form of an oxide.
