"Becquerel rays" is an earlier term for what is now known as radioactivity. They are the emissions of energy and particles from the decay of unstable atomic nuclei, discovered by Henri Becquerel in 1896. These rays can be harmful to living organisms and have important applications in medicine, industry, and research.

History of radioactivity?
Radioactivity was discovered by Henri Becquerel in 1896 when he observed that uranium salts emitted rays that could expose photographic plates. Marie and Pierre Curie further studied these rays and discovered the elements polonium and radium, leading to the development of the field of radioactivity. This discovery revolutionized science, leading to advancements in both nuclear physics and medical treatments.
What did Henry Becquerel invent?
Henry Becquerel did not invent anything; he discovered radioactivity in 1896. This groundbreaking discovery paved the way for further research into nuclear physics and its applications in various fields. Henri Becquerel was awarded the Nobel Prize in Physics in 1903 along with Marie and Pierre Curie for their work on radioactivity.
How was becquerel convinced atfirst thathis hypothesis was supported?
Becquerel was convinced that his hypothesis was supported when he observed that photographic plates wrapped in opaque material were still fogged after being exposed to uranium salts. This suggested that an invisible form of radiation was being emitted from the uranium, supporting his hypothesis that certain materials could emit energy without external stimulation.
What scientists were involved in the discovery of radioactivity?
Marie Curie, Pierre Curie, and Henri Becquerel were key scientists involved in the discovery of radioactivity in the late 19th and early 20th centuries. Marie Curie's work with radioactive materials led to her pioneering research on radioactivity for which she was awarded Nobel Prizes in Physics and Chemistry.
What experiments did becquerel perform?
Henri Becquerel performed experiments that involved exposing uranium salts to sunlight and observing their ability to fog photographic plates wrapped in light-proof paper. He discovered that the uranium salts emitted radiation that could penetrate opaque materials and affect photographic plates. This accidental discovery led to the development of the field of nuclear physics.
What did Henri becquerel discover?
Henri Becquerel discovered in 1896 the natural radioactivity.
Who is Becqueral?
Becquerel discovered x-rays and radioactivity in 1896.
What are the works of Antoine Henri Becquerel?
He discovered rays, invisible to the eye but NOT xray or cathodrays (have been discovered prior) but radioactive rays.
What was the first thing that Marie curie discover?
The first thing Marie Curie discovered was Becquerel's rays but called it radioactivity after her home land.
Did Henri Becquerel and the Curies find out that the atoms werent indivisible?
The work of Henri Becquerel discovered uranium rays. Marie Curie used them in her work and helped to discover evidence that atoms may not have been the simplest blocks of matter and could in fact be divided.
Contribution of Henri becquerel?
Henri Becquerel discovers the radioactivity.
What was discovered by Henri becquerel?
Henri Becquerel discovered radioactivity
When did Jean Becquerel die?
Jean Becquerel died in 1953.
When was Jean Becquerel born?
Jean Becquerel was born in 1878.
What has the author Karl Papius written?
Karl Papius has written: 'Das Radium und die radioaktiven Stoffe' -- subject(s): Radium, Radioactivity, Becquerel rays
How did Antoine Becquerel improve the atomic theory?
Antoine Becquerel discovered radioactivity in 1896, which led to the development of the subatomic theory. This discovery provided evidence that atoms are composed of smaller particles, like protons, neutrons, and electrons, and helped expand our understanding of the structure of atoms and their behavior.
How do minerals containing uranium darken photographic film?
Emitting alpha particles and gamma rays. These rays affect the photographic emulsion. The natural radioactivity of uranium was discovered by Henri Becquerel in 1896.
