History of Radioactive Elements
In 1896, French physicist Henri Becquerel discovered spontaneous radioactivity in uranium salts while investigating a connection between phosphorescence and x-rays, which had just been discovered. Becquerel had been studying fluorescence and phosphorescence, a subject his father had been an expert in, and was skilled in photography. He found that the uranium salts emitted radiation without any stimulation from sunlight and confirmed that uranium was the element emitting the radiation. Becquerel’s discovery was accidental but significant and led to the study of other radioactive elements by Marie Cuire and Pierre Curie, who coined the term “radioactivity.” The accidental discovery of radioactivity is well-known in the history of physics.
Radioactive Elements in Periodic Table
Radioactive Elements are the elements that emit radioactive waves like alpha waves, beta waves, and gamma waves. The Process is called Radioactivity. They are found throughout the Earth’s crust and have important applications in various fields, including medicines, energy production, etc. The radioactive elements are unstable because of the presence of excess nuclear charge inside their atomic nucleus. These atomic nuclei undergo radioactive decay to form stable nuclei. The elements that undergo radioactive decay are called radioactive elements.
