Which is the best description of a molecule?

Lewis structure – Wikipedia

VSEPR theory – Wikipedia

A molecule 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.. In quantum physics organic chemistry and biochemistry the distinction from ions is dropped and molecule is often used when referring to polyatomic ions.. In the kinetic theory of gases the term molecule …

Lewis structures also known as Lewis dot formulas Lewis dot structures electron dot structures or Lewis electron dot structures (LEDS) are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule . A Lewis structure can be drawn for any covalently bonded molecule as well as coordination compounds.

Fri Nov 14 2003 13:30:00 GMT-0500 (Eastern Standard Time) · A biomolecule or biological molecule is a loosely used term for molecules present in organisms that are essential to one or more typically biological processes such as cell division morphogenesis or development. Biomolecules include large macromolecules (or polyanions) such as proteins carbohydrates lipids and nucleic acids as well as small molecules such as primary …

The methane molecule (CH 4) is tetrahedral because there are four pairs of electrons. The four hydrogen atoms are positioned at the vertices of a tetrahedron and the bond angle is cos −1 (− 1 ⁄ 3) ≈ 109° 28′. This is referred to as an AX 4 type of molecule. As mentioned above A represents the central atom and X represents an outer atom.

A chemical reaction is a transformation of some substances into one or more different substances. The basis of such a chemical transformation is the rearrangement of electrons in the chemical bonds between atoms. It can be symbolically depicted through a chemical equation which usually involves atom…
