Tardigrade Admin · Accepted Answer

An oxide is a a binary compound of oxygen with another element or group.
Chemical formula for cuprite is

Cu_{2} O

and chemical formula of argentite is

Ag_{2} S

.
Therefore, Argenite is not an oxide. Cuprite is an oxide mineral.
Therefore, given statement is incorrect.
