Bohr proposed adding to the model the new idea of quanta put forth by Max Planck in 1901. That way, electrons existed at set levels of energy, that is, at fixed distances from the nucleus.

In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't quite right. By all rules of classical physics, it should be very unstable. For one thing, the orbiting electrons should ...

In 1913, Niels Bohr revised Rutherford's model by suggesting that the electrons orbited the nucleus in different energy levels or at specific distances from the nucleus. By doing this, he was able ...

特斯拉Model Y定位于为中型SUV，同时也是特斯拉的第五款量产车型，其基于Model 3平台开发而来，因此设计风格上与Model 3十分相似。尽管外观很相似，但是车身尺寸方面，Model Y确实要比Model 3要实在很多，Model Y比Model 3长了56mm、宽了71mm、高了181mm、轴距长了15mm ...

Model United Nations is a popular, internationally known academic activity that encourages students to learn more about international relations, diplomacy as well as how the UN operates.

Niels Bohr adapted Ernest Rutherford's nuclear model. Bohr did calculations that led him to suggest that electrons orbit the nucleus in shells. The shells are at certain distances from the nucleus.

Antiferromagnets are materials in which the magnetic moments of neighboring atoms are aligned in an alternating pattern, resulting in no net macroscopic magnetism. These materials have interesting ...
