Bohr`s Model of the Atom - Mr. Walsh`s AP Chemistry
... The Bohr Model of the Hydrogen Atom The Bohr model worked well for hydrogen. However, the equations could not be solved exactly for atoms with more than one electron, because of the additional effects that electrons exert on each other (Coulomb force kq q F d12 2 ). By the mid-1920s, quantum physi ...

For the first time, physicists have measured changes in an atom to the level of zeptoseconds, or trillionths of a billionth of a second – the smallest division of time yet observed. In this case, the speed demon was an electron escaping the bonds of its parent ato ...
