If by "pair atoms" you mean molecules, and by potassium and oxygen you mean potassium oxide, then molecules can not be described as metals or nonmentals. Potassium is a metal, while oxygen is nonmetal.
Oxygen is a nonmetal. Oxygen 2 is a molecule composed of two oxygen atoms, and like all oxygen atoms, it is classified as a nonmetal on the periodic table.
In a binary compound made from potassium and oxygen (potassium oxide), the ratio of potassium atoms to oxygen atoms is 4:2, which can be simplified to 2:1. This means there are twice as many potassium atoms as there are oxygen atoms in the compound.
In a binary compound of potassium and oxygen (potassium oxide), each potassium atom combines with one oxygen atom to form K2O. Therefore, the ratio of potassium atoms to oxygen atoms is 2:1.
A compound containing potassium and oxygen atoms would have a formula of K2O, and would be named potassium oxide. This is a binary ionic compound.
As indicated by the subscript on the atomic symbol for oxygen, there are 3 oxygen atoms.
The number of potassium and oxygen atoms in a binary compound depends on the specific compound. For example, in potassium oxide (K2O), there are 2 potassium atoms and 1 oxygen atom. In potassium chloride (KCl), there is 1 potassium atom and 1 chlorine atom.
Potassium chlorate (KClO3) has 3 oxygen atoms.
In the compound Cu₂O, there is one nonmetal atom, which is oxygen (O). The formula indicates two copper (Cu) atoms, which are metals, and one oxygen atom. Therefore, the total count of nonmetal atoms is one.
1:2 --- Three potassium oxides are known: - K2O: 2 potassium atoms and 1 oxygen atom - KO2: 1 potassium atoms and 2 oxygen atoms - K2O2: 2 potassium atoms and 2 oxygen atoms
The formulae for potassium nitrate is 'KNO3' This tells us that there is one atom of potassium , one atom of nitrogen and three atoms of oxygen. #So yes!!! there is oxygen present in potassium nitrate.
In Potassium Sulphate there are two atoms of potassium, one atom of sulphur and four atoms of oxygen so there are 7 atoms and three elements.
There are 2 potassium atoms, 1 carbon atom and 3 oxygen atoms - K2CO3
