The relationship between atoms and molecules is the way molecules are made up of atoms. Atoms that are in groups of two or more are called molecules. More »

Electronegativity in atoms causally relates to polarity in molecules, as different electronegativities in different components of an asymmetrical molecule cause that molecule to be polar. However, electronegativity diffe... More »

Density and mass are mutually dependent physical properties, with density being equal to the amount of mass per unit of volume of any particular object or substance. The mass of any object depends entirely on its overall... More »

In 1905, Albert Einstein published an analysis in which he devised a mathematical way to predict the size of both atoms and molecules. At the time, the science of atoms was still in its infancy, but Einstein's test was c... More »

In chemistry, 6O2 is six molecules of O2, which equals 12 atoms of oxygen. The "O2" is a molecule of oxygen gas, while the "6" indicates that there are six such molecules. More »

Atoms and molecules both make up matter in the universe, but atoms make up molecules. In order to form molecules, atoms form bonds. More »

Carbon is present in a wide variety of molecules because its atomic structure makes it extremely easy to form bonds. Carbon readily bonds with multiple other atoms, and it can form chains of bonds with other carbon atoms... More »
