non exclusion principle

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..

Thus, the Pauli's exclusion principle may also be stated as "An orbital can have maximum of two electrons and these two must have opposite spin". The maximum number of electrons in each main energy level can be predicted by extending this principle. The tabular column ..

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 opposite spi..

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. Electrons havi..

No two atoms can have the same quantum state. Hence, all electrons have discrete energy states. If there are 'n' orbits, then there are 2n possible energy levels which are splitting and creating a band of energy (electrons possessing a range of energy level..

There are 109 elements known at present. 92 elements occur in nature, while the rest are man-made. All materials on the Earth are made of these naturally occurring elements. These are classified into metals, non-metals, and metalloids. The occurrence and extraction of some lighter m..

The kingdom Mycota includes exclusively the fungi. The fungi are a group of organisms which has a plant body called thallus that may be unicellular or multicellular. They are achlorophyllous and non-vascula..

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 first. This is in accordance with Aufbau principle as already di..

It is the study of principles and practices of cultivating useful varieties of plants - ornamental plants, flowering and non-flowering plants, vegetatively reproducing plants, vegetables and fruit..

Introduction - Chemical reactions mostly take place in solutions. Solution chemistry plays a very significant role in chemistry. All chemical substances are made up of either polar units (called ions) or non-polar units. The activity of these entities is more evident and pronounced in sol..
