An electron from a new atom would have to join an atom in the H 2 molecule on the next energy level, further from the nucleus where it would not feel a strong enough attraction. An electron from an ...

Since it has 1 more electron than protons, chlorine has a charge of –1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full. For example, when ...

An electron makes its escape It's like catching light in action. For the first time, physicists have measured changes in an atom to the level of zeptoseconds, or trillionths of a billionth of a ...

In a discovery that brings a legendary quantum theory to life, physicists at Princeton University have directly observed Hofstadter’s butterfly — a fractal pattern in electron energy levels ...

Positronium is composed of an electron, with a negative charge, circling in orbit with a positron, with a positive charge — making what’s effectively an atom without a nucleus (SN: 9/12/07).

Vaishnav and Clark's proposal begins with an atom--rubidium-87 is an example--that has a 'tripod' arrangement of electron energy levels, consisting of one higher energy level above three equal ...

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 ...

If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in the energy levels ...
