practical period-was traced back during the prehistoric times when primitive men were pre occupied for survival
-marked the use of fire& production of metals, pottery,wine making, etc
-was based from the practical experience of primitive men w/o reference from the underlying principles of science
-to prevent sickness, they became expert in making medicine w/ the use of the roots and other parts of plants...(medicine,marked the beginning of chem. process)
philosophical period-dominance of greek philosophies
-used logic and reason in exploring the natural phenomena
-3 phases of matter was discovered

-atomic theory of democritus
`the seeds were considered atoms
3.period of alchemy
-by the religious mysticism of Egypt
-transmutation of common metal into gold
-iatrochemistry
-Robert boyle criticized chemistry
4. phlogiston period
by george ernst stahl
the first great principle in chemistry
5.modern times chemistry
experimentation had been gaining acceptance to the community
Antoine lavoisier-father of modern chemistry
what were five periods in the development in chemistry?
identify the stgae of the development of chemistry?
I. Age of Philosophers II. Age of Alchemy III. Age of Iatrochemistry IV. Age of Combustion V. Age of Modern Chemistry
There are five major subdivisions of chemistry. These subdivisions of chemistry include analytical, inorganic, organic, physical, as well as biochemistry.
Is organic Chemistry,Inorganic Chemistry,Biochemistry,Analytical Chemistry and Physical chemistry
organic chemistry , inorganic chemistry, physical chemistry,analytic chemistry ,biochemistry
There are only four periods in the history of Chemistry. The Black Magic, Alchemy, Traditional chemistry and Modern chemistry.
the three stages in the history of chemistry are th ff:
Paleolitic-paleos means old and lithic means stone.
Groups are columns and periods are rows in the periodic table of Mendeleev.
Physical chemistry Analytical chemistry Organic chemistry Inorganic chemistry Materials chemistry
give me five professions that use chemistry?
Development of medicines is essentially a chemical factor, or a chemistry issue. Can you quote any medicine in which chemicals, therefore, chemistry, are not involved ?
Chemistry has more than five divisions; it is impossible to say that a chapter of chemistry is the most fundamental.
