What is quntam numbers?

Quantum numbers can be defined as a number that occurs in the hypothetical expression for the value of some quantized property of a subatomic particle, atom, or molecule and can only have certain integral or half-integral values.


What is a fermion?

a small land mammal such as a rat mouse ferret mole ect. A fundamebtal particle with half-integral spin, such as an electron.


If the spin of one electron orbital is clockwise what is the spin of the other electron in that orbital?

According to Pauli's Exclusion principle it will be having anticlock wise spin if it is in the same orbital. Because no two electrons can have all the four(always spin is half) quantum number same. By the way, I don't think anyone actually calls them "clockwise" and "counterclockwise". It's usually "up" and "down" or "plus one-half" and "minus one-half".

How many electrons do atoms want in their outermost energy level?

The answer is Valence Electrons. Atoms want a full number of electrons in their outer shell, which is why atoms with only one electron missing from their outer shell are most reactive, because they are close to completing that shell. Electrons as such are half-spin particles or fermions. A single particle electron orbital (intended as a solution of a 1-D Schrödinger equation) with occupancies 0 and 1 can have 2 allowed quantum states. Electrons are seen as indistinguishable particles in quantum mechanics. In other words electron 1 is the same as electron 2. We can then state that any electron of appropriate energy will be able to occupy the outermost shell of an element.

What are redox half-reactants?

The first half reaction concerns oxidant takenig up (an) electron(s), the other half is the one with a reductant producing (an) electron(s).


What is a bispinor?

A bispinor is an object which is used to describe quantum fields having half-spin.


The spin of one electron in an orbital is clockwise what is the spin of the other electron in that orbital?

actually they don't rotate at all (what is clockwise or anticlockwise for an electron anyway? what's the reference frame?). there's no rotation in the subatomic level. even if there were any, we wouldn't be able to detect it. roj


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.


Why does nitrogen have a half filled electron shell?

Electron configuration for N (at. no. 7) is 1s2 2s2 2p3 so the 2p orbital, which can hold 6 electrons, is only half full. Is that what you are asking?
