hund's rule of multiplicity

Hund's Rule of Maximum Multiplicity - 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..

It states that when more than one orbital of equal energies are available then the electrons will first occupy these orbitals separately with parallel spins. The pairing of electrons will start only after all the orbitals of a given sub level are singly occupied. This is because electrons with par..

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

Events are said to be independent if the occurrence of one event does not affect the occurrence of others. If A and B are two independent events, then This is known as Multiplication Rule of Probability . The converse is also true, that is if two events A ..

In the multiplication or division of numbers, the final result should be reported up to the same number of significant figures as are present in the term with the least number of significant figure..

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. 2. Each molecular or..

The longest continuous carbon chain containing the multiple (double or triple) bonds is selected. It is to be remembered that the parent chain must contain double or triple bond even if it is not the longest chain in the formula. For example, On the basis of the number of ..

The factors of a number can be obtained through _______________ rules. => Divisibility or Multiplication or Factorization or None of the above..

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 into the 2p orbital as 2p subshell can accommodate..

.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 multi..
