This 'solar system' model of the atom is the way that most people think about atoms today. It is known as the Rutherford-Bohr model of atomic structure.

In the earliest attempts at this model, scientists took their inspiration from the solar system, which has a dense "nucleus" (the sun) surrounded by a "cloud" of smaller particles (the planets ...

Wanderers CU is a responsive sound experience delivered via a mobile app that responds to the visitor’s movement as sensed by GPS. A complement to the Colorado Scale Model Solar System represented by ...

Scientists have predicted for a long time that elements with around 164 protons could have a relatively long half-life, or even be stable.

For example, the oxygen atom has eight electrons, the atom of iron has 26 electrons. Once Bohr tried to use his model to predict the spectral lines of more complex atoms, the results became ...

A mind-bending hypothesis is gaining traction among scientists: The universe may be teeming with microscopic black holes the size of an atom, but with the mass of a city-sized asteroid. Created ...

If microscopic black holes born a fraction of a second after the Big Bang exist, as some researchers suspect, then at least one may fly through the solar system per decade, generating tiny ...

Black holes the size of an atom that contain the mass of an asteroid may be flying through the inner solar system about once a decade. Theoretically created just after the big bang, these examples ...
