A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. 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 monatomic molecules. A molecule may be homonuclear , that is, it consists of atoms of one chemical element , as with oxygen O 2 ; or it may be heteronuclear , a chemical compound composed of more than one element, as with water H 2 O. Atoms and complexes connected by non-covalent interactions , such as hydrogen bonds or ionic bonds , are typically not considered single molecules.

Neutrons and electrons are found in space as a cloud around the nucleus. The nucleus contains all the positive charge of an atom. Electrons surround the nucleus and account for the majority of an atom's volume. ANS: D 2. Atoms consist of three fundamental particles. What are these particles and their charges? Rank the subatomic particles from least to greatest mass.
