according to the aufbau principle

Aufbau Principle - 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 o..

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 orbitals with..

Uncertainty Principle - All moving objects in our daily life have well defined paths or trajectories. The path or trajectory of an object can be determined by knowing its position and velocity at various intervals of time. However, Werner Heisenberg, in 1927, pointed out that we can never..

Pauli's Exclusion Principle - According to this principle, an orbital can accommodate maximum of two electrons and these two must have opposite spins. This means that an orbital can have 0, 1 or 2 electrons. Moreover, if an orbital has two electrons, they must be of op..

Principle of Fax Machine - The essential parts of a fax system are the transmitting devices that translate the graphic material into electrical impulses according to a set pattern, and a synchronized receiving device that retranslates these impulses and prints that. In a typical..

The following rules are followed for filling up molecular orbitals with electrons in order to write molecular configurations: 1. The molecular orbital having the lowest energy is filled first. This is in accordance with Aufbau principle as already discussed for atoms. ..

According to the modified cell principle, new cells arise only from pre-existing cells. Cells transfer their genetic information only by way of cell divisio..

According to the principle of reversibility of light, the path of a ray of light is reversible. The figure below shows how light gets refracted from medium 1 to medium ..
