IPA: /həʊməˈnjuːklɪə/
KK: /həˈmoʊnəˌkjulər/
Describing a molecule that consists of atoms from only one type of element, or having identical nuclei.
The homonuclear molecule was studied for its unique properties.
Homonuclear → It is formed from "homo-" (from Greek "homos", meaning same) and "nuclear" (from Latin "nucleus", meaning kernel or core). The word "homonuclear" refers to a molecule that contains atoms of the same element, hence the idea of being composed of the same type of nuclei.
Think of 'same' ('homo-') atoms in a 'core' ('nucleus') — that's why homonuclear means having the same type of nuclei.
