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.
The best Theory gives the most reliable answer that is based upon unsinkable evidence.
As it should be.
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.
Creationism is a belief system that asserts that the universe and living beings originate from specific acts of divine creation. From a scientific perspective, creationism is considered a myth rather than a theory because it lacks empirical evidence and does not adhere to the scientific method of investigation and naturalistic explanations.
in d orbital and f orbital there is a full filled & half fulled stability
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.
Molecular orbital theory(MOT) provides information about both molecular shape and molecular bonding.
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 depends on the molecular orbital theory
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.
