Which describes the experiments of becquerel and the curies? becquerel showed that uranium requires x-rays to form radiation, and the curies coined the term “radioactivity.” becquerel coined the term “radioactivity,” and the curies showed that uranium requires x-rays to form radiation. becquerel discovered other radioactive elements, and the curies showed that uranium gave off radioactivity. becquerel showed that uranium gave off radioactivity, and the curies discovered other radioactive elements.

Henri Becquerel was a French physicist who in 1896 discovered a new property of matter (which was later called radioactivity). This was accidentally observed when Becquerel found out that uranium salt was spontaneously emitting some kind of rays that went through different substances and were able to veil even a photographic film.

Then the marriage of Marie and Pierre Curie caried out more experiments to study, in a quantitative way, the radiation emitted by the salts Becquerel studied cualitatively, and other salts that contained uranium. During this process they found other radioactive substances, such as: thorium, polonium and radium.

For that reason, the three of them were awarded the Nobel Prize in Physics in 1903 for their discovery of radioactivity.
