concept of orbital

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 and are called o..

The orbital concept of hyperconjugation is well illustrated with the help of propene. In this, the electron pair of C-H bond ( s - bond) is involved in conjugation with the p -electron pair of the double bond. In hyperconjugation the delocalisation of s -electrons of H-C bon..

The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus in certain well-defined circular orbits. But the idea of uncertainty in position and velocity ov..

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..

An atom is made up of three particles, electrons protons and neutrons. Electrons have a negative charge and protons have a positive charge whereas neutrons have no charge. They are neutral. Due to the presence of equal number of negative electrons and positive protons the atom as a whole is elect..

Probability Picture of Electrons and Concept of Atomic Orbital (Wave Mechanical Treatment) - The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus..

Hybridisation is the phenomenon of redistribution of energies of the orbitals of slightly different energies so as to give a new set of orbitals of equivalent energies. The new orbitals are called hybrid or hybridised orbitals. The number of hybridized o..

Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence bond theory in terms of the quantum mechanica..

In the physical sense, y gives the amplitude of the wave associated with the electron. It is known that in case of light waves, the square of the amplitude of the wave at a point is proportional to the intensity of light. Extending the same concept to electron wave motion, the squ..
