Molecules with the same atoms in different arrangements are called isomers. Also carbohydrates, for example, have the same ratio (carbon:hydrogen:oxygen= 1:2:1) (and thus the same empirical formula) but different total numbers of atoms in the molecule. See more A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics See more The definition of the molecule has evolved as knowledge of the structure of molecules has increased. Earlier definitions were less precise, defining … See more Molecules as components of matter are common. They also make up most of the oceans and atmosphere. Most organic substances are molecules.
