Originator of modern atomic theory which states that matter is composed of atoms that can not be further subdivided. Each
- each element consists of atoms with identical properties and mass,
and compounds are formed when atoms of different elements combine in a
fixed composition. 
An Italian scientist who sparked through hopotesisnya Avogadro's law
that "at the same pressure and temperature, the gases have the same
volume the same number of particles". 
A scientist who succeeded in extracting metals sodium and potassium from hidroksidanya through electrolysis. He is known as a pioneer of electrolysis of the research results. 
A scientist who formulated the law of conservation of energy, namely "Energy can neither be created nor in musnakan". 
An English scientist who proposed the event of light scattering by colloidal particles known as Tyndal effect. Tyndall effect can be used to distinguish sistemkoloid and true solution. 
Chemist
who is known as the ring because it successfully reveals how the six
carbon atoms of benzene molecules bind to the six hydrogen atoms. 
Scientists
from Britain who argued that merukana cathode ray particles are
negatively charged, has mass, and is owned by all the material. 
A
French chemist who did research on chemical equilibrium, and present
one of the equilibrium principle is "if the action is something done a
certain equilibrium, then the equilibrium will be shifted to eliminate
the impact of the action". 
A scientist Sweden who got Hadia Nobel Prize for his work on ionization. He
suggested that the compounds in solution can be decomposed into ions
her, and the strength of the acid in solution aqua depending on the
concentration of hydrogen ions in it.
