Quantum Mechanical Model of the Atom - Two new theories came to substantially modify Bohr's Atomic model. They a..

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: ..

Breathing Mechanism - The physical movements associated with the gaseous exchange are called breathing. The various structures that are involved in the breathing mechanism are the respiratory passage, the lungs, the outer and inner intercostal muscles, the diaphragm and the musc..

In the nineteenth century scientists saw enough evidence to prove that each element has its distinctive atom. But all tem atoms contain identical electrons. In spite of the fact that electrons carry negative charge, atoms as whole were found to be neutral. This led to the fact that atoms must conta..

We have seen in the previous lesson that a current carrying conductor when kept in a magnetic field experiences forces and torques. Is reverse phenomenon possible? If we rotate the coil in a magnetic field, will current flow in the coil without we passing it? The answer is yes. Current ca..

Probability Picture of Electrons and Concept of Atomic Orbital (Wave Mechanical Treatment) - The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus in certai..

Viscosity - When two solid surfaces slide over each other, a frictional force acts between them that opposes the relative motion of the bodies. Similarly, when a layer of a liquid slips on another layer the two exert a tangential force on another. This opposes their motion. The property of a liquid..

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 quantu..

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..
