Some molecules consist of two atoms of the same element. For example, O 2 is the oxygen molecule most commonly found in the earth's atmosphere; it has two atoms of oxygen. However, under certain circumstances, oxygen atoms bond into triplets (O 3), forming a molecule known as ozone.
Small nonpolar molecules such as molecular oxygen, carbon dioxide and molecules consisting of mostly hydrocarbons move through the membrane easily while polar molecules do not.
