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 ...

The technology, enabled by thorium atoms, could keep time more accurately than atomic clocks and enable new discoveries about gravity, gravitational waves and dark matter Shi En Kim Reporter ...

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 1815, for example, Berzelius isolated a new element from a mineral sent to him from the Swedish mining town of Falun and named it thorium after the Scandinavian god of thunder, Thor. Only to ...

Developed in the late 1920s, Bohr's theories didn't include a formal model of the measurement process, but did highlight a ...

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 ...

While uranium reactors depend on solid fuel rods, thorium reactors use an environmentally safer liquid mixture of fuel that ...

Before you start cutting up that ‘negative ion’ health bracelet or personal massager, be aware that these are highly likely to contain thorium oxide or similar radioactive powder, as this ...

What's New for 2024? The Model 3 has received a welcome styling refresh for 2024, complete with a sleeker front end, a quieter cabin, and updated standard features. While the changes to the Model ...

The verdict: Tesla’s comprehensive overhaul to the suspension, interior and user interface of the Model 3 makes it not just one of the best electric vehicles available, but one of the most ...
