What are the assumptions of quantum mechanics?

In a particular representation and applied to a system consisting of a single, structure-less particle the fundamental assumptions of Quantum Mechanics are: The quantum state of a particle is characterized by a wave function Ψ(r,t), which contains all the information about the system an observer can possibly obtain.

What is the law of quantum physics?

The theory allows particles to be created and destroyed and requires only the presence of suitable interactions carrying sufficient energy. Quantum field theory also stipulates that the interactions can extend over a distance only if there is a particle, or field quantum, to carry the force.

Can a particle be at rest according to quantum mechanics?

1) For a particle to be at rest, we would know its momentum and therefore by Heisenberg’s uncertainty principle, the uncertainty in its position would be infinite. Is this acceptable? 2) λ=h/p=h/0⟹λ→∞ which is not possible.

What does quantum mechanics have to do with the concept of an atom?

quantum mechanics, science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.

Can a particle ever be at rest?

If a particle has no mass (m = 0) and is at rest (p = 0), then the total energy is zero (E = 0). But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest. But light is not the only massless object.

Can a particle be at rest?

Common sense says a particle is at rest when its velocity is 0 (i.e., not moving). The particle is at rest after 1 seconds and 3 seconds.

How does treating the electron as a wave rather than as a particle solve the riddle of why electron orbits are discrete?

How does treating the electron as a wave rather than as a particle solve the riddle of why electron orbits are discrete? Electron orbits can only hold an integer number of wavelengths of the electron standing wave. Like a paper clip chain necklace circumference is equal to a multiple of the single paper clip length.
