. have also dual character. In other words, the microscopic particles in motion possess both the particle and wave characteristics. Thus, according to de-Broglie, "all material particles in motion possess wave characteristics". According to de-Broglie, the wavelength associated with a particle of h..

Derivation of de-Broglie Relationship - The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of frequency n as: E = h n .....(1) Acc..

where, y = (psi) is a wave function of space coordinates 'x', 'y', 'z' and represents the amplitude of the electron wave. m = mass of the electron E = the total permissible energy level, which the electron can have. V = potential energy of the electron given by ze 2 /r. h = Planck..

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 which electrons revolve in definite circular paths cal..

Summary - Dalton had postulated that matter is made up of atoms, which are indivisible. Thomson was the first to suggest a structure for an atom. According to him, an atom is a positively charged sphere of radius=10 - 1 0 m in which the mass and the positive charge of the atom are uniform..
