The belief that electricity flows out from a negative source seeking a positive conclusion.
How atoms are arranged in a molecule.
write note on free electron theory
Electronic theory is the theory of the behavior of the electron under various conditions including a free electron, a bound electron in either an outer or inner orbit of the atom.
we describe air by answering it's properties
the same way an insulator and a conductor will work with out the electron theory!
when data shows electron energy levels are not related to light wavelengths.
An electron configuration shows the distribution of electrons among the subshells. Each number shows the principal quantum number, or shell, the subshell and finally the orbital of the electron.
There is no single unified theory that explains all correlated electron systems.
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.
The VSEPR (Valence Shell Electron Pair Repulsion) theory predicts molecular shapes based on the repulsion between electron pairs around the central atom. It uses the number of electron groups surrounding the central atom to determine the geometry of the molecule.
free electron model not take into account the potential neither the electron interaction. nearly free electron take into account the potential.J.C. Aguiar
