Silver is a chemical element with the symbol Ag and atomic number 47. A soft, white, lustrous Unlike the preceding transition metals, the +1 oxidation state of silver is stable even in the absence of π-acceptor ligands. Silver does not react
Silver Oxide is an odourless, fine black or dark brown cubic crystals. The chemical formula is Ag 2 O. When the aqueous solutions of silver nitrate and alkali hydroxide reacts together, Silver Oxide is produced. Its IUPAC name is Silver(I) oxide and density is 7.14 g/cm 3. It is soluble in acid, alkali and insoluble in ethanol. In silver processing: Chemical compounds Silver oxides (both Ag 2O and AgO) serve as the cathodic materials in silver-zinc primary and secondary (i.e., rechargeable) batteries.

Silver also finds use as a catalyst for its unique ability to convert ethylene to ethylene oxide, which is a precursor of many organic compounds. Silver is one of the noblest—that is, least chemically reactive—of the transition elements. There are two oxides of silver: Ag2O and Ag2O2 (AgO). Ag2O is brownish black, but Ag2O2 is grayish black. In other words, they look pretty much the same. In a thin film they are both grey to black, depending on thickness. Most of the time, the discoloration of silver is due to the formation of silver sulfide, Ag2S, which is grey black. Silver(I) oxide is soluble in alkali solution and may contain corresponding dihydroxoargentate(II) in solution or form silver hydroxide. This can be used to describe the amphoteric character of silver(I) oxide as it also reacts with acid to form silver chloride. $$\ce{Ag2O + 2NaOH <=>[H2O] 2Na[Ag(OH)]}$$ Source

Silver oxide is used as the base in special cases of Suzuki–Miyaura cross-couplings as, for example, in reactions with n-alkylboronic acids ((62)229 and (63)230), including MeB(OH)231,232 —which have been considered as substrates of low nucleophilicity, giving low yields of cross-coupling products under standard conditions. Silver oxide can be prepared by combining aqueous solutions of silver nitrate and an alkali hydroxide. 2 AgOH → Ag 2 O + H 2 O ( pK = 2.875) US patent 20050050990 describes the preparation of Ag 2 O with properties suitable for use as a fine grained conductive paste filler.
There is the expected Ag2O, described at Silver oxide - Wikipedia, consisting of Ag(1+) and O(2-) in a cubic structure. The more unusual has an empirical formula AgO, which would be expected to be Ag(2+)O(2-), which would have an unpaired 4d9 electron configuration with an unpaired electron that would make the Ag paramagnetic.

Silver(I) oxide ≥99.99% trace metals basis Synonym: Argentous oxide, Disilver monoxide, Disilver oxide CAS Number 20667-12-3. Empirical Formula (Hill Notation) Ag 2 O . Molecular Weight 231.74 . EC Number 243-957-1. MDL number MFCD00003404. PubChem Substance ID 24853593. NACRES NA.23 Silver(I,III) oxide is the inorganic compound with the formula Ag 4O 4 . It is a component of silver zinc batteries. It can be prepared by the slow addition of a silver(I) salt to a persulfate solution e.g. AgNO 3 to a Na 2S 2O 8 solution. It adopts an unusual structure, being a mixed-valence compound.
