3.2 Bohr`s Model of the Atom
... The movement of an electron from one energy level to another is called a transition The ground state is the lowest energy state for an atom When an atom gains energy it moves into an excited state The transition from a lower energy level to a higher energy level requires a quantized amount of energy ...

... Physicists were both mystified and intrigued by Bohr’s theory. They questioned why the energies of hydrogen electron are quantized, or, why is the electron in a Bohr atom restricted or orbiting the nucleus at certain fixed distance? For a decade there is no logical explanation. In 1924, Louis de Bro ...

“solar system” model of the atom
... Periodic Table The Pauli exclusion principle states that only one electron may be in each quantum state: Only one electron at a time may have a particular set of quantum numbers, n, l, ml, and ms. Once a particular state is occupied, other electrons are excluded from that state. Therefore, if electr ...

Electrons on this surface form a two-dimensional electron gas and scatter from the iron atoms but are confined by boundary or "corral." The wave pattern in the interior is due to the density distribution of the trapped electrons. Th ...
