Chemical formula is obtained from its chemical components and their respective ratio. It also determines the number of atoms of the element and says about the name of compounds. For instance, in H2O, 2 atoms of hydrogen and 1 atom of oxygen is used.

Chemical compounds have been classified on the basis of force that binds them together. These are:

Ionic compounds are the force of positive and negative ions and this keeps the two atoms attach with each other. Ionic compounds are the combination of metals and non metals. Examples of ionic compounds are sodium chloride, aluminum oxide, sodium oxide, potassium chloride, calcium chloride, silver chloride, silver nitrate, aluminum sulfide, calcium sulphate, potassium fluoride, cobalt chloride, mercurous chloride, potassium iodide, calcium nitrate, sodium hydroxide, ammonium sulfate, ammonium fluoride, calcium fluoride, calcium carbonate and sodium bicarbonate.

Covalent compounds are attached with covalent bonds. The basic unit of covalent compound is molecule and it is also known as molecular compound. Some of the examples are sulfur dioxide, sulfur trioxide, nitrogen monoxide, nitrogen dioxide, dinitrogen pentooxide, carbon monoxide, carbon tetrafluoride, nitrogen trifluoride, oxygen difluoride and dinitrogen tetroxide. Binary covalent compounds are water, methane, ammonia, hydrazine, phospine and silane.

Organic compounds are formed of carbon molecules. Hydrogen, oxygen and nitrogen get attach with carbon to form compounds. Compounds of carbon and hydrogen are known as hydrocarbons. Examples of hydrocarbons are methane, ethane, propane, butane, pentane, hexane, heptanes, octane, nonane and decane. Other organic compounds are alkanes, alcohols, aldehydes, amines, imines, esters, acetic anhydrides, phenols, amides, ketones, ethers, furans, azides, halogen compounds, nitro compounds, organometallic compounds, alkaloids, terpenoids, cyanides, pyridine, pyrimidines and purines.
