One is the answer at high school.
Silver has a number of valencies:-
1 - the most common, AgCl, AgBr, Ag2O are examples thi is the one to remember!
2 - AgF2 is known
3- Ag2O3 is known
There are three silver oxides, two that appear in the text books Ag2O and AgO and a new one reported in 2003, Ag3O4
In Ag2O the most familiar silver has a valency of one. Its systematic name is silver(I) oxide.
AgO looks as if it is silver(II) oxide, in fact it is NOT. Its systematic name is silver (I,III) oxide. This is a mixed valence compound with silver exhibiting valencies of 1 and 3.
Ag3O4 is silver (II,III) oxide. This is a mixed valence compound with silver exhibiting valencies of 2 and 3.
The valency of silver as an element is zero. When combined in a salt, it is 1+.
1
Silver oxide is a compound.
Silver rust
Silver oxide is an ionic compound so its molecular and empirical formula is same Ag2O
silver nitro-oxide
Silver oxide is a chemical compound. It is used to prepare other silver compounds. Source: Wikipedia. The link below has more information on Silver Oxide.
1 is the valency of silver
+2
+2 is the valency of nitrogen in compound HNO3(nitric acid)
Since valency of oxide is 2 which is formed when electrons are gained by oxygen , hence valency of oxygen is also 2
Because here nitrogen has a lower valency of 1
It is silver oxide that is Ag2O.
The symbol of oxide is "O" and that of peroxide is "O2"but the valency of both these radicals is 2
Its Valency = 2the formula being CuOThe copper donates two electrons to the oxygen and forms one ionic bond.Added:There are two copper oxides, differing in color:if it is black powder, then it is copper(II) oxide CuO (cupric, more common, as in the mineral 'tenoriet')if it is red powder, then it is copper(I) oxide Cu2O (cuprous oxide, as in mineral the 'cupriet' and it occurs in 'Benedict's test' on reducing sugars)
The symbol of Silver is Argentum or Ag and valency is positive 3
The best known oxide of silver is Ag2O
No, it isn't. Silver Oxide is a compound. Silver is an element.
The chemical formula for silver(I) oxide is Ag2O.The chemical formula for silver(II) oxide is AgO.
