What is the difference between quantum mechanics and quantum physics?
Quantum Mechanics is a branch of physics describing the behavior of energy and matter at the atomic and subatomic scales. It explains it itself and Quantum Physics is the same deal. They're just two different ways in saying it.
What is a measure of electrical energy called?
Electrical energy is measured in the same units as any other type of energy: joules.
What particle do you use to keep a wormhole stable?
In order to keep a Wormhole stable you need something called ''Exotic Matter''. Exotic matter is not the same as antimatter. It consists of particles that have negative energy or mass. Negative energy makes sense in the context of quantum theory, because the energy density of the quantum vacuum is actually positive (instead of zero). A region of "negative" energy density is actually a region with a positive energy density below that of the quantum vacuum. It is possible to create such regions using photons trapped between parallel plates (the Casimir effect). It is also possible to create such a region using particles of a so-called scalar field, such as the Higgs boson being searched for with the Large Hadron Collider. I got this from a recent book on wormhole physics (The Physics of Stargates -- Parallel Universes, Time Travel, and the Enigma of Wormhole Physics, by Enrico Rodrigo, 2010)
What is the relationship between an electron's location and the energy it has?
An electron can be located in any of several energy levels around the nucleus of an atom. Usually, an electron will occupy the "ground state," which is the lowest energy level available. Electrons can be thought of as being lazy, which means they don't want to work any harder than they have to; and occupying the ground state amounts to the path of least resistance. Occasionally, however, an electron can "bump up" to a higher energy level. It can do this by absorbing energy from an outside source, such as an electrical current. It will occupy this higher energy level for a certain amount of time, then drop back to its ground state, releasing that same energy it absorbed to get there. The amount of energy absorbed is called a quantum. Often, the electron will release that quantum of energy as a photon, which is a "bundle" of light. Billions of photons can be a light that you can see, and this is how neon lights and glow sticks work. So the higher an energy level an electron occupies, the higher its energy.
How did Max Planck's discovery help people?
Photo electric emission was successfully explained by Albert Einstein only because of Max Planck's discovery of quantum concept. Einstein got Nobel prize for the same. Niel Bohr made his postulates just imitating the concept of quantum mechanics. So he was able to measure the radius of the atom. His quantum concept has opened the door for uncertainty principle.
What states that no two electrons can have the same energy level?
The Pauli exclusion principle states no two electrons can have the same energy level. More exactly it states that no two electrons can have the same set of quantum numbers.
Why the pauli exclusion principle is called as exclusion principle?
Pauli's principle states that no two electrons in the same atom can occupy the same quantum state, so that excludes the possibility of two electrons having the same quantum state in an atom
Elements are placed in the same column of the periodic table because their outer electrons are in the same energy level?
Yes, they're called shells (according to the simpler atom model; the adjective 'outer' is referring to that) or orbitals (quantum energy model, cf. the term 'energy level').
Why can't an atom's electrons ever be located between orbits?
We have learned from the subject of quantum mechanics that energy exists in discrete packages called quanta. You cannot have a half a quantum of energy, the universe is not constucted that way. The farther an electron is from the nucleus, the more potential energy it has (in the same way that an elevated object has gravitational potential energy) and that energy comes in specific quanta. Therefore, electrons can only have specific orbital distances. Any other distance would require a fraction of a quantum of energy, which is not allowed.

What is Fermionic repulsion pressure described by quantum mechanics?
Fermions are particles with half spin for example, electrons. Pauli's exclusion principle states that no more than two fermions can occupy the same energy state. from Quantum mechanics, electrons will also fill up all energy levels until the Fermi Energy. If you compress these electrons further, the total fermi energy of the system is increased (not the individual fermions) and work must be done to compress these fermions. As a consequence, the fermions exert an opposing pressure, called the fermionic repulsion pressure.
What are degenerate energy states how zeeman effect remove degeneracy?
Two or more different states of a quantum mechanical system are said to be degenerateif they give the same value of energy upon measurement. The number of different states corresponding to a particular energy level is known as the degeneracy of the level, as zeeman effect split the spectral lines in to several components having slight differences in freguency, as frequency corresponds to energy I think in this way degeneracy of energy levels is removed.
What is poly's exclusion principle?
It's called Pauli (http://en.wikipedia.org/wiki/Wolfgang_Pauli) exclusion principle and it states that no two identical fermions may occupy the same quantum state simultaneously.
What is the main difference between Classical free Electron theory and Quantum free Electron theory?
Electrons are fermions and thus cannot occupy the same quantum states. They obey Fermi-Dirac statistics, and will occupy energy levels accordingly. This is different to the classica state where all electrons are pretty much equal (equal energies etc) and are not taken to be distrubuted amongst multiple states and energies. See Fermi Gas Model for a treatment of quantum free electron theory.
The Pauli exclusion principle states that?
Simple stated, no two electrons can have the same quantum numbers. Electrons at the same level would have a + and - spin.
Is optic computer and quantum computer the same?
HECK NO! An optics computer is a computer running on light, but a quantum computer is a computer where most components are at a quantum-Hall state of matter (hey did you know that there are more than 15 states of matter). In other words, optic computer=light, quantum computer=weird.
Why do two electrons in the same orbital have to have opposite spin states?
Yes. Always. Otherwise they would break the fundamental rules of quantum mechanics, which say that no two electrons can have the same four quantum numbers -- and spin is the 4th quantum number. If two e- are in the same orbital, they share 3 quantum numbers, but the spin quantum number must then be different.
