Question

Advantages and disadvantages of quantum mechanic physical chemistry ​

Answer 1

Explanation:

Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

Answer 2

Answer:

♤ Quantum mechanics is a theoretical framework which specifies the kind of forms that physical laws must take. It does not have advantages and disadvantages in the utilitarian sense of the term. If you mean when is it practical to use quantum mechanics instead of classical mechanics, then there is no such sharp boundary as such. Classical Mechanics is an approximation of quantum mechanics in the limit of high quantum numbers. As you probe smaller range of dimensions of space and time , you have to add more and more quantum "corrections" to the classical laws. At some point, it will be pragmatic to abandon the whole structure of classical reasoning and resort to a full blown treatment of the system with the mathematical formalism of quantum mechanics.
