A molecule (/ˈmɒlɪkjuːl/ from Latin moles "mass") is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge. However, in quantum physics, organic chemistry, and biochemistry, the term molecule is often used less strictly, also being applied to polyatomic ions.
In the kinetic theory of gases, the term molecule is often used for any gaseous particle regardless of its composition. According to this definition, noble gas atoms are considered molecules as they are in fact monoatomic molecules.
A molecule may be homonuclear, that is, it consists of atoms of a single chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O). Atoms and complexes connected by non-covalent bonds such as hydrogen bonds or ionic bonds are generally not considered single molecules.
my room's the universe. i lay here on the floor and look up at the stars and my mind is fine for a little while. my room's the universe. i sit and play guitar and my gut isn't hurting now. i lay down. i breathe in and out; in and out for a little while. my room's the universe and i'm a molecule. a simple molecule. my room's the universe and i am dust.
