WebbRadioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation.A material containing unstable nuclei is considered radioactive.Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and … WebbMarch 1, 1896: Henri Becquerel Discovers Radioactivity. In one of the most well-known accidental discoveries in the history of physics, on an overcast day in March 1896, French physicist Henri Becquerel opened a drawer and discovered spontaneous radioactivity. Henri Becquerel was well positioned to make the exciting discovery, which came just a ...
WebbStable nucleus – non-radioactive . Unstable nucleus – radioactive . Keep in mind that less stable means more radioactive and more stable means less radioactive. We want to know why there is a radioactivity. What makes the nucleus a stable one? There are no concrete theories to explain this, but there are only general observations Webbрадиоактивная теория

WebbThe radioactive atoms decay, they argued, each decay signifying the transmutation of a parent into a daughter element, and each type of atom undergoing its transformation in a characteristic period. This insight set the course for their next several years of research, for the task was then to order all the known radioelements into decay series and to search …
