atomic energy levels

Single electron atoms - The relative energies of various orbitals of single electrons depend on the value of the principal quantum number 'n' and is independent of the value of 'l'. This can be shown by an arrangement known as energy level diagram. The diagra..

Energy Level Diagram for Molecular Orbitals - The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (ii) the extent of overlapping between the..

The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (ii) the extent of overlapping between the atomic orbitals. The greater the overlap, the more the ..

Atomic Spectra - A spectrum is an assembly of energy levels in the form of radiations emitted by an atom in its excited state. Every atom gives discontinuous line spectra. Each line in the spectra corresponds to a specific wavelength and it is uniqu..

A spectrum is an assembly of energy levels in the form of radiations emitted by an atom in its excited state. Every atom gives discontinuous line spectra. Each line in the spectra corresponds to a specific wavelength and it is unique to a given element...

Valence band and the conduction band lies in the energy gap. According to the Bohr's theory, free electrons in an isolated atom have certain definite discrete amount of energy. If large number of atoms are brought close to one another to form a crystal, they..

Electronic Configurations of Atoms - The distribution of electrons in different orbitals is known as electronic configuration of the atom. The orbitals are indicated by a box (square or circular) and electrons are indicated by arrows. An empty square will mean an empty orbital, ..

Based upon the rules and sequence of energy levels, one can write the electronic configurations of atoms of some rows of the periodic tabl..

Rutherford's model had a major drawback. It could not explain why ultimately electrons did not fall into the nucleus by taking a spiral path. This was in concurrence with the electromagnetic theory that states 'if a charged particle undergoes accelerated motion then it must radiate energy..

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..
