What did Henri Becquerel accomplish?
For his discovery of spontaneous radioactivity Becquerel was awarded half of the Nobel Prize for Physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation.

What did Henri Becquerel do for the atom?
Like Thomson’s discovery of the electron, the discovery of radioactivity in uranium by French physicist Henri Becquerel in 1896 forced scientists to radically change their ideas about atomic structure. Radioactivity demonstrated that the atom was neither indivisible nor immutable.
Who discovered artificial radioactivity?
THE DISCOVERY OF ARTIFICIAL RADIOACTIVITY In January 1934, Irene Curie and Frederic Joliot discovered artificial radioactivity. By bombarding a sheet of Aluminium-27 with a particles, they observed the creation of a new radioactive isotope, or radioisotope, Phosphorus-30.
Who discovered alpha beta and gamma rays?
physicist Ernest Rutherford
Six years after the discovery of radioactivity (1896) by Henri Becquerel of France, the New Zealand-born British physicist Ernest Rutherford found that three different kinds of radiation are emitted in the decay of radioactive substances; these he called alpha, beta, and gamma rays in sequence of their ability to …
Who discovered gamma rays Henri Becquerel?
Henri Becquerel discovered this phenomenon while investigating the properties of fluorescent minerals. One of the minerals Becquerel worked with was a uranium compound. Uranium ore produces naturally occurring gamma radiation.
What is artificial radioactivity used for?
Artificially radioactive isotopes can be used in the treatment of disease as well as in its diagnosis. For example, an artificially radioactive isotope of cobalt is used to treat some types of cancer patients. The radiation from the cobalt damages cancerous cells and may prevent the spread of the disease.
Who discovered y rays?
Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900, while studying radiation emitted from radium.
Who discovered the plum pudding model?
Joseph John Thomson
Thomson’s “Plum Pudding” Model. In 1897, Joseph John Thomson (1856–1940) had announced the discovery of a corpuscle. Others soon called it ► electron, despite Thomson’s stubborn preference for his original term, borrowed from Robert Boyle (1627–91) to denote any particlelike structure.
How did Becquerel discover gamma rays?
Gamma rays were discovered shortly after the discovery of X-rays. In 1896, French scientist Henri Becquerel discovered that uranium minerals could expose a photographic plate through another material. Becquerel presumed that uranium emitted some invisible light similar to X-rays, which W.C.
Who discovered the three types of radiation?
Six years after the discovery of radioactivity (1896) by Henri Becquerel of France, the New Zealand-born British physicist Ernest Rutherford found that three different kinds of radiation are emitted in the decay of radioactive substances; these he called alpha, beta, and gamma rays in sequence of their ability to …
What did Antoine Becquerel discover?
Antoine Henri Becquerel ( / ˌbɛkəˈrɛl /; 15 December 1852 – 25 August 1908) was a French engineer, physicist, Nobel laureate, and the first person to discover evidence of radioactivity. For work in this field he, along with Marie Skłodowska-Curie (Marie Curie) and Pierre Curie, received the 1903 Nobel Prize in Physics.
Why did Henri Becquerel win the Nobel Prize for Physics?
His research in the field of radioactivity won him the Nobel Prize for Physics in the year 1903. Henri Becquerel was deeply associated with the National Musuem of Natural History when his father was the chair of physics and following his stellar work as a researcher he became the chair of physics at the same institution.
When did Georges Becquerel die?
In 1903, Becquerel received the Nobel Prize in Physics for his research on radioactivity along with Pierre and Marie Curie. He died in Le Croisic, France on August 25, 1908.
Where was Antoine Becquerel born and raised?
Childhood & Early Life Antoine Henri Becquerel was born to Alexandre-Edmond Becquerel and Aurelie Quenard in Paris, France, on 15 December, 1852. His father was a scientist and employed as a professor of Applied Physics. He belonged to a family of distinguished scholars and scientists.
