All the q-th roots of z lie on a circle centred at the origin O and having radius equal to the real, positive q t h root of r. One of them has amplitude q /q and others are uniformly spaced around the circle separated from others by an angle 2p ..

Argand diagram of the q th roots of a Complex number - All the q-th roots of z lie on a circle centred at the origin O and having radius equal to the real, positive q t h root of r. One of them has amplitude and others are uniformly spaced around the circle separated from others by an angle..

To use this theory for predicting the shapes of molecules, the number of electron pairs (both, shared and lone pairs) is simply counted. This is illustrated by taking a typical molecule of the type AB n . 'A' is the central atom, 'B' atoms are bonded to 'A' by single covalent h..

The VSEPR theory, proposed by R.J.Gillespie and R.S. Nyholmm in 1957, is based on the repulsions between the electron-pairs in the valence-shell of the atoms in the molecule. It was developed to predict the shapes of the molecules in which the atoms are bonded to..

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..

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 m..

Metallic Bond (Band Theory) - Metals constitute about three fourths of all the known elements. They have characteristic properties such as bright luster, high electrical and thermal conductivity, malleability, ductility and high tensile strength. The attractive force, which bind..

Metals constitute about three fourths of all the known elements. They have characteristic properties such as bright luster, high electrical and thermal conductivity, malleability, ductility and high tensile strength. The attractive force, which binds various metal atoms, is called metallic ..

Main Postulates - I) The metal ligand bond arises by donation of pair of electrons by ligands to the central metal atom. II) To accommodate these electrons the metal ion must possess requisite number of vacant orbitals of equal energy. These orbitals of the metal atom undergo hybridisatio..
