Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. Learn more about the properties and structures of molecules in this article.

A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O 2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (two hydrogen atoms and one oxygen atom; H 2 O).

A molecule is defined as an electrically neutral group of two or more atoms connected by chemical bonds. Here are examples of molecules and a look at the difference between a molecules, compounds, and ions.

A molecule is made up of atoms of one or more elements. For example, aluminum is a pure element whose molecule is made up of a single element. Likewise, a molecule of helium consists of a single atom of the element helium. On the other hand, an oxygen molecule is made up of two atoms of the element oxygen.

Molecules (ISSN 1420-3049, CODEN: MOLEFW) provides an advanced forum for science of chemistry and all interfacing disciplines. Our aim is to provide rigorous peer review and enable rapid publication of cutting-edge research to educate and inspire the scientific community worldwide.

molecule. It permits simulation of the coupled dynamics of valence electrons and ionic cores in a molecule or a material. From the Cambridge English Corpus. In addition, the dielectric constant in the pore region should be set to 1 where the water molecules are represented explicitly (but see discussion below).

Molecules is a peer-reviewed open access scientific journal that focuses on all aspects of chemistry and materials science. It was established in March 1996 and is published monthly by MDPI. From 1997 to 2001, Molbank was published as a section of the journal, before splitting into its own journal. The editor-in-chief is Farid Chemat.
