filling the orbitols by electrons using hund's rule

Electron pairing will not take place in orbitals of same energy (same sub-shell) until each orbital is first singly filled with parallel spi..

According to this rule, electron pairing will not take place in orbitals of same energy (same sub-shell) until each orbital is first singly filled with parallel spin. In other words in a set of orbitals having same energy (degenerate orbitals), the electrons..

According to this rule, electron pairing will not take place in orbitals of same energy (same sub-shell) until each orbital is first singly filled with parallel spin. In other words in a set of orbitals having same energy (degenerate orbitals), the electrons ..

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 f..

.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 r..

In lithium (Z =3), the third electron goes to the next 2s orbital. In Beryllium (Z = 4), the fourth electron fills 2s orbital and in boron (Z = 5), the next electron goes to the next available 2p orbital. In carbon, the sixth electron is also to go ..

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 the molecular orbitals, which are asso..

>The electronic configuration of the molecule is: O 2 : KK( s 2s) 2 ( s *2s) 2 ( s 2p z ) 2 ( p 2p x ) 2 ( p 2p y ) 2 ( p *2p x ) 1 ( p *2p y ) 1 Thus oxygen molecule has two bonds (one s and other p ). Further, in accordance with Hund's rule the last two electron..
