The chemical formula for potassium oxide is K2O.
Potassium oxide is an inorganic compound consisting of potassium and oxygen. In the formula K2O, the ‘K’ represents potassium, while the ‘O’ represents oxygen. The subscript ‘2’ indicates that there are two potassium atoms for every one oxygen atom in the compound.
In chemical terms, potassium belongs to Group 1 of the periodic table, and it typically forms a +1 charge when it reacts. Oxygen, on the other hand, is found in Group 16 and usually forms a -2 charge. When potassium and oxygen react, two potassium ions (K+) combine with one oxide ion (O2-) to form potassium oxide, hence the formula K2O.
