Its oxide must be X2O.
The correct formula for copper(I) cyanide is CuCN.
Bi, Bismuth forms the most basic oxide in group 5A because it has the most metallic character.
No. It is not. Iron is an element. Oxygen is an element. Iron Oxide is a compound.
OF2 is the formula for fluorine oxide.
Al2O3 is the chemical formula of aluminium oxide.
Fe2O3.
Silicon. Its chemical formula is SiO2.
O2- is the formula for oxide ion. The negative symbol indicates the presence of anions and 2 represents the oxidation state.
Calcium oxide chemical formula is CaO so calcium and oxygen is present.
The correct formula for copper(I) cyanide is CuCN.
The formula is MgO, which represents a ratio of 1:1.
MnO
Bi, Bismuth forms the most basic oxide in group 5A because it has the most metallic character.
There are a number of chemical compounds conmade up from iron and oxygenIron(III) oxide, ferric oxide, is Fe2O3Iron(II)oxide, ferrous oxide, FeOiron(II,III) oxide, ferrous ferric oxide, Fe3O4
It stands for Potassium oxide. It isn't an element, it's a compound.However the correct formula for potassium oxide is K2O and not KO.
Group 2
It's a compound. Its formula is HgO, which is a combination or two or more elements.
