filling electron orbitals

Rules for Filling Molecular Orbitals - 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 firs..

Each molecular orbital can accommodate maximum of two electrons having opposite spins. This is in accordance with Pauli's exclusion principl..

The general electronic configuration of d-block elements is (n-1) d 1-10 ns 1-2 . All the d-block elements except zinc, cadmium and mercury have partially filled d-orbitals. But, zinc, cadmium and mercury have completely filled d-orbitals and they e..

Molecular orbital theory was proposed by F. Hund and R.S. Mulliken in 1932. The basic idea of molecular orbital theory is that atomic orbitals of individual atoms combine to form molecular orbitals. The electrons in molecules are present in th..

(a) Formation of a planar hexagonal structure due to overlapping of the sp 2 hybrid orbital of each carbon atom with its neighboring carbon atoms and hydrogen atoms. (b) A unhybridized 2p orbital on each carbon lies perpendicular to the carbon-carbon plane. Out of the three hybr..

.6 - Energy level diagram for a multi-electron atom The energy level diagram for a multi-electron atom is as shown above. The filling of orbitals is governed by the following rules: 1) Aufbau principle 2) Pauli's exclusion principle 3) Hund's rule of maximum ..

Atomic Orbitals - Electrons cannot exist at a particular point or in a well-defined orbit (path), according to the above new approach called wave mechanics. This led to the concept of 'most probable regions'. We talk about 'certain regions in space around the nucleus c..

According to wave mechanics, we cannot simply say that the electron exists at a particular point but we talk about certain regions in space around the nucleus where the probability of finding the electron is maximum. Such regions are expressed by mathematical expressions a..
