What does argentic mean?
Argentic is a technical adjective used in chemistry to describe compounds in which the metal silver occurs in its divalent state — that is, with an oxidation number of +2. Because silver far more commonly forms +1 compounds, the term is reserved for relatively rare species such as argentic oxide (AgO) and argentic fluoride (AgF₂), which are notable for their strong oxidizing power. The word derives from Latin 'argentum', meaning silver, and pairs with its counterpart 'argentous', which labels the more familiar monovalent silver(I) compounds. Largely confined to inorganic chemistry textbooks and older scientific writing, argentic is unfamiliar to most general readers but remains a precise and useful label wherever the distinction between silver's two common oxidation states matters.
adjectiveRelating to or containing silver in its divalent (two-plus) state; used chiefly in chemistry to describe silver(II) compounds such as argentic oxide.
- Describing silver in the +2 (divalent) oxidation state in chemical compounds.
"Argentic fluoride, in which silver takes the +2 oxidation state, is a rare and powerful oxidizing agent."
"The argentic ion Ag²⁺ is a strong oxidizer found in only a handful of stable compounds."
"Early photographic processes exploited the difference between argentous and argentic salts of silver."
Silver usually shows up as +1 in chemistry — but when it goes +2, chemists call it 'argentic', a term borrowed straight from Latin 'argentum'.

Etymology of argentic
Argentic comes from Latin 'argentum', the classical word for silver, combined with the adjectival suffix '-ic' used in chemistry to mark the higher of two oxidation states. It was coined within the nomenclature system that also produced 'argentous' ('-ous' marking the lower, +1 state). The same Latin root gives English words such as 'argent' and 'argentine', both referring to silver or silver-like qualities.

How argentic is actually used
Strictly a technical chemistry term, encountered almost exclusively in inorganic chemistry and historical scientific literature. It contrasts with 'argentous', which denotes monovalent silver(I). Outside these contexts the word is essentially obsolete.
Easily confused with argentic
Argentous describes silver in its +1 (monovalent) state, whereas argentic describes silver in its rarer +2 (divalent) state.
