Molecular science. The science of molecules is called molecular chemistry or molecular physics, depending on whether the focus is on chemistry or physics.Molecular chemistry deals with the laws governing the interaction between molecules that results in the formation and breakage of chemical bonds, while molecular physics deals with the laws governing their structure and properties.

At the heart of chemistry are substances — elements or compounds— which have a definite composition which is expressed by a chemical formula.In this unit you will learn how to write and interpret chemical formulas both in terms of moles and masses, and to go in the reverse direction, in which we use experimental information about the composition of a compound to work out a formula.

Tutorial on Chemical Bonding, Part 1 of 10 (Introduction) It is probably more useful to regard a chemical bond as an effect that causes certain atoms to join together to form enduring structures that have unique physical and chemical properties. So although the "chemical bond" (as a physical object) may be no more than a convenient fiction, chemical bonding, which leads to the near-infinity.

In chemistry, the empirical formula of a chemical is a simple expression of the relative number of each type of atom or ratio of the elements in the compound. Empirical formulas are the standard for ionic compounds, such as CaCl 2, and for macromolecules, such as SiO 2.An empirical formula makes no reference to isomerism, structure, or absolute number of atoms.
