Circa 400-5 BCE (Greek Philosopher Democritus)
a. Suggested the idea of subject being comprised of
small , indivisible, indistructible allergens (atomos)
installment payments on your Lavoisier (18th century)
a. proposed the law of preservation of mass
matter cannot be created or damaged
atoms cannot be made or demolished in a
reaction, they are simply rearranged
to form new chemicals
a. proposes the law of definite proportions/Law of
given mixture will always develop the same
amount of chemical substance elements by mass.
four. Englishman Steve Dalton (19th Century)
a. formulated the Atomic Theory (aka: Dalton's Atomic
concludes the following
1 ) Matter is composed of tiny debris
2 . Almost all atoms of a given aspect are
3. The atoms of any given component are
unlike those of any other
4. Atoms of different factors combine
in small , complete number percentages to form
chemical substances. A given chemical substance
always has the same relative amounts
and types of atoms (Law of Definite
Proportions), but several
compounds made up of the same
components can be created, by
combining elements in different small

EX. 1) 12 grms of carbon dioxide can match 16 grams of oxygen to form co2 monoxide(CO), nevertheless 12 grams of carbon can lso combine with thirty-two grams of oxygen to create carbon dioxide (CO2). The ratio of o2 masses that combine with doze grams of carbon is definitely 16: 32 or you: 2 (whole number ratios)
Experimental Facts for the Atomic Style:

formulated, in the late nineteenth and twentieth centuries that began to recognize the subatomic particles that comprise the atom
