WebAtoms can combine in many different ways as molecules. The same atoms may combine in different proportions to form different molecules. As an example, two hydrogen atoms and one oxygen atom form water (H 2 O), while two hydrogen atoms and two oxygen atoms form hydrogen peroxide (H 2 O 2 ). WebWhen atoms combine through chemical bonding, they form compounds—unique structures composed of two or more atoms. The basic composition of a compound can be indicated using a chemical formula. A chemical formula uses symbols from the periodic …
