When oxygen combines with 2 hydrogens it makes water.
The oxygen molecule is two(2) atoms of oxygen doubly bonded together. Structurally, ' O = O '. Ozone molecule is three(3) atoms of oxygen singly bonded to each other. Any one oxygen atoms forms two single bonds , one each with the other two oxygen atoms. Structurally it is a 'Triangular' shape. NB Oxygen and Ozone are ALLOTROPES of each other; NOT isotopes. It is the same atom (oxygen(O)), in a different structural arrangement, and thereby exhibiting different physical characteristics.
The metals by themselves do not have chemical formulas, they have chemical symbols which are shown on the periodic table of the elements. They only have chemical formulas if they are chemically bonded to another element, usually a nonmetal.

The term "ternary" refers to compounds that consist of three elements. In the context of chemical formulas, ternary compounds typically include combinations of a metal, a nonmetal, and oxygen, such as in oxoacids (e.g., sulfuric acid, H₂SO₄) or salts (e.g., sodium sulfate, Na₂SO₄). These compounds often contain a central atom bonded to oxygen and another element, forming a variety of chemical species.

The large numbers in front of some chemical formulas are called coefficients. They represent the ratio of moles of each substance in a chemical reaction and are used to balance the equation.
