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..

The first four pairs of spiracles are involved in inspiration or drawing in of air (that is oxygen-rich). This air passes through the trachea and the air sacs to reach the tracheoles. Mechanism of Respiration in Insects The ends of the tracheoles are filled with fluid. This end enter..

In this, the patient lies down surrounded by massive electromagnets and is exposed to short bursts of powerful magnetic field and waves. These bursts stimulate the protons (hydrogen nuclei) of the patients tissues to emit radio signals which are picked up and converted into digital signals. These ..

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 numbers. Each electron in an atom i..
