It was first based on spectroscopic observations, but now is based on quantum mechanics.
Molecular orbital theory determines molecular structure that the electrons are not assigned as individual bonds between atoms, however, are treated as moving under the influence of the nuclei in the whole molecule.
As it should be.
In molecular orbital theory, a node is a point in a molecular orbital where the probability of finding an electron is zero. Nodes help determine the shape and energy of the molecular orbital, influencing the chemical properties of the molecule.
The Revealed Prfeference Theory has been propunded by Prof.Samuelson. This theory has been based upon behaviorial ordinal oproach.This theory known as Consumption theory and different from Hicks and Marshall utility theory of the demand.
Gilbert Lewis followed by Linus Pauling who is credited with the quantum mechanical approach, called valence bond theory (distinguishing it from the more recent molecular orbital theory), which is based on Lewis's electron pair bonding theory now taught as Lewis "dot" diagrams.
A subtheory (sub-theory) is a theory which is based upon, or largely contained within, a larger theory. For instance, in my own field of sociology, value conflict theory might be considered a subtheory of conflict theory. Similarly, social exchange theory is a subtheory of social behaviorism.
i am not sure but i think it was " Lorentz" plese check this and reply me it is true right or not.
It is the current working theory of the origin of the universe. It is the paradigm that Astronomy is based upon. But, new evidence is always being described. The theory itself might change as our knowledge grows.
it depends on the molecular orbital theory
In modern quantum-based atomic theory, the space around the nucleus in which an electron moves is known as an electron cloud or orbital. This is a region of space where there is a high probability of finding the electron. The electron cloud is described by the probability density function of the electron's position in the atom.
Orbital hybridization provides information about both molecular bonding and molecular shape.
The name given to a particular space around the nucleus in which an electron moves is Orbital
