Who is the DJJ Thomson?
Sir Joseph John “J.J.” Thomson, OM, FRS (18 December 1856 – 30 August 1940) was a British physicist and Nobel laureate. He discovered the electron and isotopes, and invented the mass spectrometer.
What is J.J. Thomson’s theory?
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.”
What is an interesting fact about J.J. 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.
Where did J.J. Thomson go to school?
Joseph John Thomson was born in Cheetham Hill, a suburb of Manchester on December 18, 1856. He enrolled at Owens College, Manchester, in 1870, and in 1876 entered Trinity College, Cambridge as a minor scholar.
What experiment did JJ Thomson conduct?
The experiment Cathode Ray Tube (CRT) conducted by J. J. Thomson, is one of the most well-known physical experiments that led to electron discovery. In addition, the experiment could describe characteristic properties, in essence, its affinity to positive charge, and its charge to mass ratio.
What was the name of the experiment JJ Thomson did?
Cathode Ray Experiment
Thomson’s First Cathode Ray Experiment His first experiment was to build a cathode ray tube with a metal cylinder on the end. This cylinder had two slits in it, leading to electrometers, which could measure small electric charges.
Who invented atom in India?
Acharya Kanada
Acharya Kanada, also known as Kashyapa, an ancient Indian natural scientist and philosopher, formulated the theory of atoms 2500 years before John Dalton’s discovery. He founded the Vaisheshika school of Indian philosophy that epitomized the earliest Indian physics.
Who discovered photon?
At the dawn of the 20th century, Max Planck and Albert Einstein turned physics on its ear by introducing the notion of quanta.
Who was Joseph Thomson?

Sir Joseph John Thomson OM PRS (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be discovered.
What did JJ Thomson study in college?
Joseph John Thomson, always known as “J. J.,” was born in Manchester, England, on December 18, 1856. His fame derives primarily from his discovery of the electron in 1897. He studied physics and mathematics, first in Manchester, and in 1876 went to Trinity College, Cambridge University, and never left.
What was the personal life of JJ Thomson like?
Education and personal life. His mother, Emma Swindells, came from a local textile family. His father, Joseph James Thomson, ran an antiquarian bookshop founded by a great-grandfather. He had a brother, Frederick Vernon Thomson, who was two years younger than he was. J. J. Thomson was a reserved yet devout Anglican.
