In addition to Thomson himself, six of his research assistants (
Charles Glover Barkla, Niels Bohr
, Max Born, William Henry Bragg, Owen Willans Richardson and Charles Thomson Rees Wilson) won Nobel Prizes in physics, and two (Francis William Aston
Who did JJ Thomson work with?
Thomson worked in
the Cavendish Laboratory
after graduation, under the tutelage of Lord Rayleigh. He quickly earned a membership in the prestigious Royal Society and was appointed Rayleigh's successor as the Cavendish Professor of Physics at the age of 28.
Did JJ Thomson work with other scientists?
J. J. Thomson died at age 83, on August 30, 1940. His ashes were buried in the Nave of Westminster Abbey, joining other science greats such as Isaac Newton, Lord Kelvin, Charles Darwin, Charles Lyell, and his friend and former research worker Ernest Rutherford.
What is Ernest Rutherford known for?
Ernest Rutherford
postulated the nuclear structure of the atom
, discovered alpha and beta rays, and proposed the laws of radioactive decay. He received the Nobel Prize in Chemistry in 1908.
Who inspired JJ Thomson?
Influenced by the work of
James Clerk Maxwell
land the discovery of the X-ray, Thomson deduced that cathode rays (produced by Crookes tube) exhibited a single charge-to-mass ratio e m and must be composed of a single type of negatively charged particle, which he called “corpuscles.” G.
Why did JJ Thomson discovered the electron?
In 1897, J.J. Thomson discovered the electron by
experimenting
with a Crookes, or cathode ray, tube. … Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles. Therefore, he proposed a model of the atom which he likened to plum pudding.
What was Rutherford's model called?
Rutherford model, also called
Rutherford atomic model, nuclear atom, or planetary model of the atom
, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford.
Who was Rutherford's student?
By 1911, after studying the deflection of alpha particles shot through gold foil, he had established the nuclear theory of the atom. One of his students,
Niels Bohr
, used Rutherford's model of the atom to describe the hydrogen spectrum in terms of the quantum theory.
When was JJ Thomson born and died?
Thomson, in full Sir Joseph John Thomson, (
born December 18, 1856, Cheetham Hill, near Manchester, England—died August 30, 1940, Cambridge, Cambridgeshire
), English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897).
What experiment did JJ Thomson do?
Summary. J.J. Thomson's experiments with
cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons
. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged “soup.”
Who is the father of neutron?
James Chadwick, in full
Sir James Chadwick
, (born October 20, 1891, Manchester, England—died July 24, 1974, Cambridge, Cambridgeshire), English physicist who received the Nobel Prize for Physics in 1935 for the discovery of the neutron.
Who discovered the electron?
Although
J.J. Thomson
is credited with the discovery of the electron on the basis of his experiments with cathode rays in 1897, various physicists, including William Crookes, Arthur Schuster, Philipp Lenard, and others, who had also conducted cathode ray experiments claimed that they deserved the credit.
How did Rutherford discover his model?
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has
a tiny and heavy nucleus
. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.
Who is the son of JJ Thomson?
They had one son, now
Sir George Paget Thomson
, Emeritus Professor of Physics at London University, who was awarded the Nobel Prize for Physics in 1937, and one daughter. For more updated biographical information, see: Thomson, Joseph John, Recollections and Reflections.
What is an interesting fact about JJ Thomson?
In 1906 he
demonstrated that hydrogen had only one electron per atom
. He designed instruments to pas cathode rays through a magnetic field and he was the first to determine the mass-to-charge ratio of cathode rays. In 1908 he was knighted for his contributions to science and in 1912 he received the Order of Merit.
