1. Molecules

   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, organic chemistry, and biochemistry, the distinction from ions is dropped and molecule is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gases, the term molecule is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, since the noble gases are individual atoms. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typically not considered single molecules.Concepts similar to molecules have been discussed since ancient times, but modern investigation into the nature of molecules and their bonds began in the 17th century. Refined over time by scientists such as Robert Boyle, Amedeo Avogadro, Jean Perrin, and Linus Pauling, the study of molecules is today known as molecular physics or molecular chemistry.

Examples of molecules in a Sentence

1. Denis Diderot:

   The following general definition of an animal: a system of different organic molecules that have combined with one another, under the impulsion of a sensation similar to an obtuse and muffled sense of touch given to them by the creator of matter as a whole, until each one of them has found the most suitable position for its shape and comfort.

2. Johan Aqvist:

   It’s all about snapping molecules together.

3. Valerie Harwood:

   Those genes are like candy. They are organic molecules and they'll be eaten up by other bacteria, other organisms, that's where the danger is - if a person then ingests that infected organism - because it will make it through their gastrointestinal tract and potentially make someone ill.

4. Zoltan Takacs:

   They target the right molecules within the human body in order to cure a disease... this makes them ideal drug leads.

5. Jason McLellan:

   Optimistically a vaccine could be created in 18 to 24 months, but this would still be extremely rapid compared to the one to two decades it normally takes, to make most vaccines. Its possible that the small molecules might be able to move quicker. There are some small molecules that have efficacy against other coronaviruses that may also work against this new coronavirus.
