For example, CuSO 4 · 5 H 2 O is "copper(II) sulfate pentahydrate." The notation of hydrous compound · nH 2 O, where n is the number of water molecules per formula unit of the salt, is commonly used to show that a salt is hydrated. The "[latex]cdot[/latex]" indicates that the water is loosely bonded to the ionic compound.
Elements. Any substance that contains only one kind of an atom is known as an element.Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P 4) or sulfur (S 8) cannot be broken down into simpler substances by these reactions.. Example: Water decomposes into a mixture of hydrogen and oxygen when an electric current is passed through the liquid.

The chemical formula is a way to represent any chemical substance using the symbol of the elements present in it. Below we have given a list of the chemical compound formulas along with the compound name, molecular weight, and molecular formula.
Mar 09, 2011· Naming basic chemical compounds is essential if you want to succeed in chemistry, since the name of the compound clearly defines what it is. Each type of compound has its own rules for naming it. When naming compounds, you need to understand these different rules, as well as how to spot clues that will help you properly name the compounds.
For example, oxalic acid, H 2 C 2 O 4, is a compound formed in plants, and it is generally considered an organic acid, but it does not contain any C-H bond. Inorganic chemistry is also closely related to other disciplines such as materials sciences, physical chemistry, thermodynamics, earth sciences, mineralogy, crystallography, spectroscopy etc.
Some organic compounds occur naturally and can be extracted from their source in an almost pure form. Rubber is an example of a naturally occurring organic compound. Other compounds are considered synthetic and have to be built up from other molecules, such as most polymers.
