drawbacks of bohr's atomic model

Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observed that some of the experimental facts regarding..

Valence band and the conduction band lies in the energy gap. According to the Bohr's theory, free electrons in an isolated atom have certain definite discrete amount of energy. If large number of atoms are brought close to one another to form a crystal, they begin to ..

Solids are substances having definite volume and definite shape. In terms of kinetic molecular model, in solids there is a regular order in the arrangement of the constituting particles (atoms, molecules or ions) i.e. the particles constituting the solids occupy fixed posi..

Quantum Theory of Covalent Bond - 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 b..

In the physical sense, y gives the amplitude of the wave associated with the electron. It is known that in case of light waves, the square of the amplitude of the wave at a point is proportional to the intensity of light. Extending the same concept to electron wave motion, the square of the wave fu..

Dual Nature of Matter and Radiation - Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observed that so..

. The atom of metallic elements contain only 1 to 3 valence electrons, therefore these atoms cannot form covalent bonds, with noble gas configurations as they will remain incomplete. Covalent compounds are bad conductors of electricity and are generally liquids; properties oppos..
