how are chemical compounds formed
Reactions and compounds. New substances are formed by chemical reactions. When elements react together to form compounds their atoms join to other atoms using chemical bonds. For example, iron and sulfur react together to form a compound called iron sulfide.Mixture of iron (grey) and sulfur (yellow) powders.Compounds usually have different properties from the elements they contain.hen elements react together to form compounds their atoms join to other atoms using chemical bonds.

A chemical compound is a chemical formed from atoms of different chemical elements. The different atoms are joined by chemical bonds. The elements stick together so strongly that the compound behaves like one substance. The chemical that is made depends upon what atoms it is made of and how they are joined together.hemists are people who study compounds and find new ways to do chemical reactions. They make chemicals in order to find new ways to do things, like to make a better glue, or to make new medicines, or to make things clean, for example.
