Nuclear power invented.

-
In 1902 Ernest Rutherford showed that radioactivity emitted an alpha or beta particle from the nucleus created a different element
-
In 1911, Frederick Soddy discovered that naturally-radioactive elements had a number of different isotopes.
-
Otto Hahn showed that the new lighter elements were barium and others which were about half the mass of uranium. Thereby demonstrating that atomic fission had occurred.
-
Nuclear fission is the subdivision of a heavy atomic nucleus such as uranium. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei. ''In 1939, Frédéric Joliot-Curie, Hans von Halban, and Lew Kowarski found that several neutrons were emitted in the fission of uranium-235, and this discovery led to the possibility of a self-sustaining chain reaction.''

In 1943, Igor Kurchatov became the director of laboratory No.2 established on the outskirts of Moscow. Where he later would create the bomb.
-
Tokaimura, Japan. The meltdown occurred after to much reactive uranium was added to a purification tank, exposing 35 people to excessive doses of radiation. Four people killed and seven seriously injured.
-
This important event relates to chemistry because the explosion happened at a nuclear plant and the chemicals had gotten too many atoms which cased too big of a reaction.
-
The nuclear plant was using uranium to power it and that relates back to when uranium was discovered in nature.
-
People care because it was a big accident that changed the course of nuclear energy and how people use it.
