Noun1.chemical science - the science of matterchemical science - the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions
electronegativity, negativity - (chemistry) the tendency of an atom or radical to attract electrons in the formation of an ionic bond
atomic mass, atomic weight, relative atomic mass - (chemistry) the mass of an atom of a chemical element expressed in atomic mass units
molecular weight, relative molecular mass - (chemistry) the sum of the relative atomic masses of the constituent atoms of a molecule
valence, valency - (chemistry) a property of atoms or radicals; their combining power given in terms of the number of hydrogen atoms (or the equivalent)
pH, pH scale - (from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic);
Dalton's law of partial pressures, law of partial pressures, Dalton's law - (chemistry and physics) law stating that the pressure exerted by a mixture of gases equals the sum of the partial pressures of the gases in the mixture; the pressure of a gas in a mixture equals the pressure it would exert if it occupied the same volume alone at the same temperature
distribution law - (chemistry) the total energy in an assembly of molecules is not distributed equally but is distributed around an average value according to a statistical distribution
equilibrium law, law of chemical equilibrium - (chemistry) the principle that (at chemical equilibrium) in a reversible reaction the ratio of the rate of the forward reaction to the rate of the reverse reaction is a constant for that reaction
Henry's law - (chemistry) law formulated by the English chemist William Henry; the amount of a gas that will be absorbed by water increases as the gas pressure increases
law of constant proportion, law of definite proportions - (chemistry) law stating that every pure substance always contains the same elements combined in the same proportions by weight
law of equivalent proportions, law of reciprocal proportions - (chemistry) law stating that the proportions in which two elements separately combine with a third element are also the proportions in which they combine together
Dalton's law, law of multiple proportions - (chemistry) law stating that when two elements can combine to form more than one compound the amounts of one of them that combines with a fixed amount of the other will exhibit a simple multiple relation
law of mass action - (chemistry) the law that states the following principle: the rate of a chemical reaction is directly proportional to the molecular concentrations of the reacting substances
Mendeleev's law, periodic law - (chemistry) the principle that chemical properties of the elements are periodic functions of their atomic numbers
natural science - the sciences involved in the study of the physical world and its phenomena
chemoimmunology, immunochemistry - the field of chemistry concerned with chemical processes in immunology (such as chemical studies of antigens and antibodies)
organic chemistry - the chemistry of compounds containing carbon (originally defined as the chemistry of substances produced by living organisms but now extended to substances synthesized artificially)
inorganic chemistry - the chemistry of compounds that do not contain hydrocarbon radicals
physical chemistry - the branch of chemistry dealing with the physical properties of chemical substances
electrochemistry - branch of chemistry that deals with the chemical action of electricity and the production of electricity by chemical reactions
femtochemistry - the branch of chemistry that studies elementary (often very fast) chemical reactions as they occur; the experimental methods are often based on the use of femtosecond laser pulses
geochemistry - the chemistry of the earth's crust
photochemistry - branch of chemistry that deals with the chemical action of light
nuclear chemistry, radiochemistry - the chemistry of radioactive substances
surface chemistry - the branch of chemistry that studies processes occurring at interfaces between phases (especially those between liquid and gas)
atomist theory, atomistic theory, atomic theory, atomism - (chemistry) any theory in which all matter is composed of tiny discrete finite indivisible indestructible particles; "the ancient Greek philosophers Democritus and Epicurus held atomic theories of the universe"
Arrhenius theory of dissociation, theory of dissociation, theory of electrolytic dissociation - (chemistry) theory that describes aqueous solutions in terms of acids (which dissociate to give hydrogen ions) and bases (which dissociate to give hydroxyl ions); the product of an acid and a base is a salt and water

That is among the conclusions in a newly-available report from top authorities on solar energy who met at the 1st Annual Chemical Sciences and Society Symposium.
Written by leading scientists in the field, including a Nobel Laureate, the papers provide a perspective on the physical and chemical sciences on the one hand, and the biological and medical sciences on the other, and will be of interest to scientists, physicians, and undergraduate and graduate students in biochemistry, structural biology, neuroscience, protein chemistry, physical chemistry, and medicine.
Sandy Dobbie, Chairman of Chemical Sciences Scotland, added: "The chemical science sector employs 14,000 people in more than 100 companies and offers a wide range of careers.
