### note

Countable: an ion, ions; «an», because it begins with a vowel sound. Pronounced EYE-on (two syllables). The word is also a suffix in many words (-ion: action, creation), but alone it is the science word. Claims that «negative ions» make you healthier are mostly advertising, not proven science.
