The properties of a compound depend upon the that are present, and the type of that exists between these different elements.

Covalent bonding happens between non- atoms. In order to obtain a full shell of outer electrons, the atoms electrons. Carbon dioxide and water are examples of covalently bonded molecutes. Many substances with covalent bonding come from organisms. All these compounds contain the element .

Covalent compounds have can be identified by their properties. They have strong covalent bonds between , and forces between the molecues. They have melting and boiling points. They can exist in a solid, or gaseous state. They are usually in water, but soluble in solvents. They are usually of electricity.

In order to investigate compounds, forensic scientists usually perform two different types of analysis. In analysis, the scientists find out which compounds are present. In analysis, the scientists find out the of each compound that is present in a sample.
