This chart shows H-index ranking of living chemists.
Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter.Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.
This list of living chemists has been compiled by Henry Schaefer, of the University of Georgia, US,together with colleague Amy Peterson. The pair assessed the h-index of around 2000 chemists; this list includes those with a score of 55 or greater.
Chemistry is sometimes called the central science because it bridges other natural sciences, including physics, geology and biology. For the differences between chemistry and physics see comparison of chemistry and physics.
The current model of atomic structure is the quantum mechanical model. Traditional chemistry starts with the study of elementary particles, atoms, molecules, substances, metals, crystals and other aggregates of matter. This matter can be studied in solid, liquid, or gas states, in isolation or in combination.
Energy and entropy considerations are invariably important in almost all chemical studies. Chemical substances are classified in terms of their structure, phase, as well as their chemical compositions. They can be analyzed using the tools of chemical analysis, e.g. spectroscopy and chromatography.
Scientists engaged in chemical research are known as chemists. Most chemists specialize in one or more sub-disciplines.
