Chemistry

From Wikinfo

Chemistry is the study of the basic atomic building blocks of nature and how they combine to form the solids, liquids, and gases that make up most forms of matter. For the many different chemical elements and compounds, see:

• The Periodic table
• List of compounds
• Inorganic chemistry, including solid state chemistry, which studies the basic principles that are applied in mineralogy and materials science
• Organic chemistry, which underlies biochemistry and polymer chemistry
• Physical chemistry, which includes computational chemistry, quantum chemistry and surface chemistry
• Analytical chemistry, the basis of environmental chemistry
