Potassium and oxygen!
Potassium oxide is the binary compound made up of potassium and oxygen.
Potassium oxide is a ionic lattice which is made out of potassium ions and oxide ions. Therefore, separate 'molecules of this compound do not exist. The empirical formula itself is K2O which is used also as the chemical formula for the compound.
Potassium oxide (K2O) is made from the combination of potassium with oxygen. There is no specific chemical compound made from potassium, oxygen, CH2, and CH3.
We use the term 'symbol' to refer to the shorthand for individual elements. Compounds have a formula made up of the symbols for the component elements with their relative numbers. For potassium oxide this is K2O.
K2O is potassium oxide
There are 2 elements in potassium oxide, which are potassium and oxygen.
K2O2 is the molecular formula for the compound potassium peroxide. Since both potassium (K) and oxygen (O) have a subscript of "2", a potassium peroxide molecule contains two potassium atoms and two oxygen atoms.
