quantum mechanics hydrogen

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: ..

Two new theories came to substantially modify Bohr's Atomic model. They a..

. The total energy of the system is equal to the sum of the energies of the two H atoms. When the two atoms approach each other, electrons of one atom attract the nucleus of the other atom. Electrons of both the atoms are attracted by both the nuclei. These attractive interactions lead to..

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. The Functioning of Tracheoles..

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..

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..

This quantum number determines the main energy level or shell in which an electron is present. It is usually denoted by n and can have any whole number value such as: n = 1, 2, 3, 4 .. etc. The various values of n as 1, 2, 3, 4 .etc., are also called K, L, M, N etc. If..

, +1 or p-subshell contains three orbitals called p- orbitals. If l=2, m may be -2, -1, 0, +1, +2 or d-subshell contains five orbitals called d-orbitals. Similarly, it can be shown that f-subshell can have seven orbitals. The number of orbitals in a subshells are given..
