Question
Elements Chart
Dmitri Mendeleev (1834 -
1907)
Dmitri Mendeleev
formulated a periodic
table similar to the one we
use today. Elements were
grouped according to
recurring trends in their
properties.

Joseph Louis Gay-Lussac
(1778 - 1850)
Gay-Lussac was a French
chemist and physicist
known best for his work
with gases and the
composition of the Earth's
atmosphere. He is credited
with the discovery of
boron. His work with
measuring alcohol and
water gave us the
measure 'degrees Gay
Lussac', which is still used
in many countries as a
measure of alcohol
content in drinks.

Marie Sklodowska Curie
(1867–1934)
Marie Sklodowska Curie
was a Polish-born French
scientist. She won the
Nobel Prize twice and was
famous for her work on
radioactivity.

Ernest Rutherford
(1871–1937)
Ernest Rutherford was a
British physicist who did
research that became the
basis for modern nuclear
physics. He was awarded
the Nobel Prize for
Chemistry in 1908.

Robert Boyle (1627 -
1691)
Robert Boyle was an
Irish-born scientist best
known for Boyle's Law of
Ideal Gases. He also was
a founding fellow of the
Royal Society of London
and an early supporter of
the atomic nature of
matter.

Sir Joseph John (J. J.)
Thomson (1884–1918)
J.J. Thomson discovered
the electron while
studying the electricity in a
cathode ray tube (CRT).
