Foreign chemists with their invention

Answer 1

Democritus (460-370B.C.)

-Greek philosopher, Developed atomic theory, -Elaborated idea that matter consisted of atoms having physical size and shape which constantly moved in a void and interacted in different ways

Daniel Rutherford (1749-1819)

-Discovered Nitrogen through experimentation with a mouse, a candle, and burning phosphorus

Robert Boyle (1627-1691)

-English physicist and chemist, Experimented in pneumatics (the study of mechanical properties of air and other gases), Through research he rejected the accepted definition of matter, -Proposed Boyle's Law (1662)

Henry Canvendish (1731-1810)

-English physicist and chemist, Discovered hydrogen (1766), Discovered nitric acid

John Dalton (1766-1844)

-English chemist and physicist, Professor of mathematics and natural philosophy (1793), Developed atomic theory, His theory (1805) accounts for the law of conservation of mass, law of definite proportions, and law of multiple proportions, Produced the first table of atomic weights

Amedeo Avogadro (1776-1856)

-His hypothesis stated that equal volumes of gases, at the same temperature and pressure, had the same amount of molecules, Avogadros number is 6.022e23, meaning that exactly 12 grams of carbon 12 has exactly 6.022e23 carbon atoms

Joseph Louis Gay-Lussac (1778-1850)

-French chemist and physicist, Developed the law of volumes concerning the combination of gases, Discovered Boron
