Atomism The idea that matter is made up of discrete units is a very old idea, appearing in many ancient cultures such as Greece and India. The word "atom" Greek:
Atomic theory gives the basic understanding about atomic structure which also presents the properties of chemical element and matter. There many atomic theory which are very influential not only for chemistry theory, bu also to other studies like biology, physics, mechanical and many others.
One of the modern atomic theory is the atomic theory by Louis de Broglie. This theory has strong relation with other previous atomic theory, especially the atomic theory from Bohr. His quantum theory is also the great addition to modify the previous mechanical quantum theory.
This article will cover the basic concept of Louis de Broglie quantum theory, its history and other important atomic theories.

He was born in France in He worked in France to perform research about general physics, including quantum theory. Louis de broglie attended Lycee Janson of Sailly to get his science degree in physics. He ever lived in the war period in At that time, he still kept his interest in science by learning some technical problems at the Eiffel Tower.
In performign this quantum theory, he greatly affected by the dualism properties of light theory. Before de Broglie, Einstein mentioned that the short wavelength of light can be observed as it consists of some particles.
Then, Louis de Broglie successfully discovered the dualism in the matter. After discovered the quantum theory, in Louis de Broglie received his first Nobel Prize for Physics.
In his hypothesis, he stated that electrons have the properties of particles and waves. He came up with this thought after the discovery of dualism in light previously. Light posses the dual properties as particle and wave. He mentioned that electrons create the waves in certain orbital around the nucleus.
He called this wave as standing wave. Standing wave has its own energy, frequency and wavelength. In his research, he tried to find out the wave properties of the matter to add the particle properties in that matter.
Louis de Broglie stated that the standing waves produced by electrons has the relation with discrete wavelength. At that time, de Broglie quantum theory gained great popularity and recognition from influential figure at that time, including Albert Einstein.
From the experiment before, we knew that electrons moved around the nucleus in the path called orbits. However, there were some restrictions to these electron movements and electron orbits.
Then, Luois de Broglie quantum theory was able to give the answer to this question at that time. The standing wave made by electrons during its movement is the cause of those restrictions.A theory is used to explain many different hypotheses about the same phenomenon or a closely related class of phenomena.
Scientific theories are well-established and highly-reliable explanations that have been verified multiple times by repeated testing and have a . 3 Louis de Broglie Quantum Theories - Applications - Atomic - Model get the explanations of some questions about the previous atomic model, especially about the electron movements here.
From decades of painstaking research from thousands of scientists, the current atomic theory builds on work done in the s by Albert Einstein, Werner Heisenberg and others.
As with the earlier theories, the atom consists of a central, heavy nucleus surrounded by a number of electrons. A theory is a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might, for example, include generalized explanations of how nature works.
The word has its roots in ancient Greek, but in modern use it has taken on several related meanings.. Theories guide the enterprise of finding facts rather than of.
