Niels Bohr was a Danish physicist who contributed to the atomic structure and theory. In 1922 he received the Nobel Prize in physics. He was also a philosopher and promoter of scientific research.
Ernest Rutherford and Niels Bohr
The Niels Bohr model shows the atom as a small, positively charged dense nucleus surrounded by orbiting electron's. He created a theory for the hydrogen atom and that energy is only transferred in certain quantities.
facts about Bohr
Bohr's experiment explains: 1. electrons would only have certain chemical motions 2. electrons in atoms orbit the nucleus that have a set size and energy 3. the lowest energy is found in the smallest orbit to another one 4. when electrons jump from an orbit to another orbit, they absorbed the radiation.
How did Niels Bohr affect us today?
Niels and Ernest Rutherford (his mentor) studied the planetary model of an atom. Bohr saw that there were some problems with Ernest's model. Rutherford believed that electrons orbit a solar nucleus, but the electron would lose energy and fall into the nucleus. Then the atoms would be unstable. So Bohr took all those issues and made his own theory.
- Bohr set off explosions in his university chemistry lab. - He won the Nobel Prize at the same time and in the same group as Albert Einstein. - Niels helped Jewish scientists escape World War II - His son also won a Nobel Prize. - An element on the periodic table was named after him.
Niels Bohr changed our daily lives a lot. He worked with atomic bombs, but soon realized that this could cause major damage to people. Bohr switched from working on the atomic bomb to promoting atomic energy in a more useful and peaceful way (NielsBohrBiography)
