jan 2, 1926 - Erwin Shrodinger
Description:
Schrodinger discovered what is known as the quantum model of the atom. The quantum theory was evolved from the Bohr theory. The Bohr theory explained simple elements such as hydrogen but not more complex elements. There was a discovery of wave-particle duality, this means that some particles were displaying wave properties this is called quantum mechanics. The quantum theory is based on the following:
1- The electrons do not orbit around the nucleus as if it were the sun.
2-You cannot determine the exact location of the electrons.
3-You can place probable locations of the electron by the energy level.
4-The energy is divided into four sub levels. Each level is made up of pairs of electrons called orbitals.
5-This model shows how the electrons in the electron clouds called orbitals.
This is still the present day atomic theory.
