quantum mechanical model of the hydrogen atom

Wave nature of material objects In 1924, de Broglie's suggested that all material objects including an electron have a dual character; they behave as particles as well as waves. The wavelength associated with a particle of mass 'm', moving with velocity 'v' is given by de Broglie's relation as: ..

Two new theories came to substantially modify Bohr's Atomic model. They a..

Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence bond theory in terms of the qu..

Schrodinger wave equation, when solved for hydrogen atom gives mathematical Y functions, which describe the allowed energy states in an atom. It is observed that physical meaningful solutions required three constants n, l and m, which are called quantum numbe..

Bohr's Atomic Model - In 1913, Neils Bohr proposed a model of an atom based on the Planck's quantum theory of radiation. The basic postulates of Bohr's theory are: An atom consists of a small, heavily positively charged nucleus around whic..

Neils Bohr was a eminent Danish Physicist who obtained his doctorate in theoretical Physics in 1911. He made a great contribution towards the understanding of atomic structure and quantum mechanics. He was awarded the Nobel Prize in Physics at the young age of 37, in 1..

Principal Quantum Number (n) - This quantum number determines the main energy level or shell in which an electron is present. It is usually denoted by n and can have any whole number value such as: n = 1, 2, 3, 4 .. etc. The various values of n as 1, 2, 3, 4 ..

The orientation of spin of an electron is designated by its spin quantum number 's'. The spin orientation is an intrinsic characteristic of the electron connected more with its magnetic behaviour rather than rotation of an electron about its own axis. This number can have only two values..
