5). Modern Atomic Model

5). Modern Atomic Model
Developed based on the theory of quantum mechanics is called wave mechanics; initiated by 3 experts:
a) Louis Victor de Broglie
States that the material has a duality that is the nature of the material and as a wave.
b) Werner Heisenberg
Propose the principle of uncertainty for the material that is as particles and waves. Distance or location of the electron-electron encircle the core can only be determined with the possibility - the possibility only.
c) Erwin Schrödinger (perfect model Bohr Atom)
Successfully preparing for the electron wave equation by using the principle of wave mechanics. Electron-electron that encircle the core there is an orbital in the 3-dimensional area around the nucleus where the electrons with a certain energy can be found with the largest possible.

Modern atomic model:
a) Atom atom consists of a core containing a proton and neutrons, while electron-electron atoms move around the core and are on the orbital-orbital particular form of skin atom.
b) Orbital 3 dimensions, namely in the area around where the core electrons with a certain energy can be found with the largest possible.
c) The position on the orbital electrons orbital-expressed with the quantum.


Orbital

 Orbital described as the electron cloud: forms a space in which electrons likely found.
 The meeting electron cloud then the more likely found electrons and vice versa.
