principle value

The principle states that the electron in an atom are so arranged that they occupy orbitals in the order of their increasing energy. Since the energy of a 'n' orbital in the absence of any magnetic field depends on the 'n' and 'l' quantum number values, the order of filling orb..

The Aufbau principle states that in the ground state of an atom, an electron enters the orbital of lowest energy first, and then the subsequent electrons are fed in the order of increasing energies into the orbitals. The relative energies of various orbitals are given in fig.1.6. From the..

If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zero. In other words, the sum of the clockwise moments equals sum of the anticlockwise moments when the body is in equilibrium. ..

The Paulis exclusion principle states, that no two electrons in an atom can have the same values of all the four quantum numbers. If one electron in the atom has the quantum numbers n = 1, l = 0, m = 0 and s = +1/2, no other electron can have the same four quantum numbers. In o..

This principle was proposed by Pauli in 1952. It states that no two electrons in an atom can have same values for all the four quantum numbers. Thus, in the same atom, two electrons may have the same values for three quantum numbers but the fourth must be different. El..

Significance of Uncertainty Principle in Daily Life - It should be borne in mind that the uncertainty is not due to lack of sufficiently refined techniques but it is due to the fact that one cannot observe microscopic things without disturbing them. No instrument can observe the position ..

It should be borne in mind that the uncertainty is not due to lack of sufficiently refined techniques but it is due to the fact that one cannot observe microscopic things without disturbing them. No instrument can observe the position of an electron without affecting its motion. In other words, unc..

1. In the principle value branches, the following formulae holds: sin -1 (sin x) = x, cos -1 (cos x) = x, tan -1 (tan x) = x, cos -1 (cot x) = x, sec -1 (secx) = x, cosec -1 (cosecx) = x 2. If a is some constant angle, then - sin q = sin a q..
