The Chemistry Portal

Shortcut: P:CHEM

Welcome to the chemistry portal. Chemistry, from the Greek χημεία meaning "pour together", is a branch of science. Modern chemistry focuses on the study of elements of the world and the bonds between elements. Chemistry also deals with composition, structure, and properties of substances and the transformations that they undergo. In the study of matter, chemistry also investigates its interactions with energy and itself. Because of the diversity of matter, which is mostly in the form of compounds, chemists often study how atoms of different chemical elements interact to form molecules, and how molecules interact with each other.

Diamond is the hardest known natural material (third-hardest known material after aggregated diamond nanorods and ultrahard fullerite), and is an allotrope of carbon. A diamond is a transparent crystal of tetrahedrally bonded carbon atoms. Diamonds have been adapted for many uses because of the material's exceptional physical characteristics. Most notable are its extreme hardness of diamond, its high dispersion index, and high thermal conductivity.

History and Philosophy of Chemistry

Many chemists have an interest in the history of chemistry. Those with philosophical interests will be interested that the philosophy of chemistry has quite recently developed along a path somewhat different from the general philosophy of science.

Other articles that might interest you are:

• Superseded chemistry theories
• Alchemy
• Scientific method
• The central science

There is a Wikipedia Project on the History of Science and a portal for the philosophy of science.

Selected biography

Freiherr Justus von Liebig (1803-1873) was a German chemist who made major contributions to agricultural and biological chemistry, and worked on the organization of organic chemistry. As a professor, he devised the modern laboratory-oriented teaching method, and for such innovations, he is regarded as one of the greatest chemistry teachers of all time. The vapor condensation device he popularized for his research is still known as a Liebig condenser, although it was in common use long before Liebig's research began. He is known as the "father of the fertilizer industry" for his discovery of nitrogen as an essential plant nutrient, and his formulation of the Law of the Minimum which described the effect of individual nutrients on crops. He also invented a process for silvering that greatly improved the utility of mirrors.
