If you were Becquerel what are some possible tests that you can do to identify the radiation emitted by uranium salt?
In the time of Becquerel only the photographic plate.
If you were Becquerel what are some possible tests that you can do to identify the radiations emitted by the uranium salt?
Becquerel in 1896 hadn't the possibility to identify the radiations emitted from uranium.
What important discovery did Becquerel make upon examining a piece of pitchblende wrapped up in paper?
Radioactivity, Becquerel concluded uranium emitted radiation without an external source such as the sun.
What did Henri Becquerel discover while studying a material that contained uranium?
Henri Becquerel discovered in 1896 the natural radioactivity of uranium.
How did Henri becquerel discover radioactivity?
In 1896, while investigating phosphorescence in uranium salts, Becquerel accidentally discovered radioactivity. Investigating the work of Wilhelm Conrad Röntgen, Becquerel wrapped a fluorescent substance, potassium uranyl sulfate, in photographic plates and black material in preparation for an experiment requiring bright sunlight. However, prior to actually performing the experiment, Becquerel found that the photographic plates were fully exposed. This discovery led Becquerel to investigate the spontaneous emission of nuclear radiation.

Why did Henri becquerel win the nobel prize?
Henri Becquerel was the first to discover that a penetrating radiation came from uranium, even if the uranium had not been exposed to sunlight. He thus showed that radioactivity was a fundamental property of uranium. Prior to his discovery, it was thought that any such radiation coming from uranium was the result of its interaction with sunlight.

Who discover the radioisotopes?
Becquerel in 1896 discovered that uranium emit radiations.
What is the name of the man who discover that the uranium was giving off radioactivity?
Uranium's radioactive properties were discovered in 1896 by Antoine Becquerel.
Is radioactive uranium positively charged?
The alpha radiation emitted from uranium isotopes is an ionizing radiation.
Did Henri becquerel discover radium and polonium?
Henri Becquerel discovered the radioactivity of uranium in 1896. Polonium and radium were discovered in 1898 by Marie and Pierre Curie.
Explain what Becquerel found out about uranium?
Becquerel discovered the natural radioactivity of uranium in 1896.
How radiation was discovered?
In 1896 Henri Becquerel was using naturally fluorescent minerals to study the properties of x-rays, which had been discovered in 1895 by Wilhelm Roentgen. He exposed potassium uranyl sulfate to sunlight and then placed it on photographic plates wrapped in black paper, believing that the uranium absorbed the sun's energy and then emitted it as x-rays. This hypothesis was disproved on the 26th-27th of February, when his experiment "failed" because it was overcast in Paris. For some reason, Becquerel decided to develop his photographic plates anyway. To his surprise, the images were strong and clear, proving that the uranium emitted radiation without an external source of energy such as the sun. Becquerel had discovered radioactivity. Becquerel showed that the radiation he discovered could not be x-rays. X-rays are neutral and cannot be bent in a magnetic field. The new radiation was bent by the magnetic field so that the radiation must be charged and different than x-rays. When different radioactive substances were put in the magnetic field, they deflected in different directions or not at all, showing that there were three classes of radioactivity: negative, positive, and electrically neutral So basically radiation was discovered by accident
