Amedeo Avogadro determines
that under the same conditions
of temperature and
pressure, equal volumes
of equal gasses contain
equal number of molecules.
The number of molecules
in one gram of a substance
is defined by the number
6.0221409×10^23,
called Avogadro's number.
Avogadro graduated college
at age 16.Henri Becquerel wins
the Nobel Prize in
Physics for discovering
radioactivity while working
with X-rays. There are
craters on the Moon and
Mars named after Becquerel.Niels Bohr wins the
Nobel Prize in physics
for his model of the atom.
"An expert is a person
who has made all the
mistakes that can be
made in a very narrow field."
-Niels BohrRobert Boyle publishes
"Boyle's Law," which
states that the volume
of a gas is inversely
proportional to its pressure.
Boyle was deeply religious,
and promoted Christianity.Robert Bunsen investigated
the light spectrum emitted
by heated elements.
Bunsen went blind in
his right eye due to a
cacodyl explosion.Henry Cavendish experimented
with metals and acids to
produce "inflammable air,"
or hydrogen, and "fixed air,"
or carbon dioxide.Marie and Pierre Curie
win the Nobel Prize in
Physics for their discovery
of radium and polonium.
Marie went on to also win
a Prize in Chemistry.
Marie Curie was the first
woman to win a Nobel
Prize, and the only person
to win two Nobel Prizes.John Dalton is best known
for his proposition of
modern atomic theory,
his law of partial pressures,
and his research in colorblindness.Humphry Davy isolates
a variety of elements
including sodium and
potassium. He is also
known for his pioneering
work in the field of electrochemistry.
Davy was popular among a female following.Otto Hahn wins the
Nobel Prize in Chemistry
for discovering nuclear
fission. Hahn is considered
the father of nuclear chemistry.
