    How Does Conjugation Lower Energy and Increase Stability in Aromatic Compounds?

    Can someone explain, possibly in layman's terms, how conjugation such as with aromatic compounds lowers the overall energy; making it more stable? Could someone also explain why aromatic compounds are more stable than through conjugation alone and what the difference is?

    Resonance Structures Chemistry: What is Potential Energy?

    I was reading this article from Wikipedia on resonance structures: http://en.wikipedia.org/wiki/Resonance_(chemistry ) What I do not understand is, what is meant by potential energy in terms of chemistry? In physics, potential energy is defined by location in a force field. What is it that...

    How exactly does momentum work?

    How exactly does momentum work? I'll use an arrow flying off a bow as an example. Does momentum increase the second it is released or does it actually increase as it flies through the air after a certain range? If because of the second part, is it due to friction from the air?

    Electron orbitals of iron and copper

    I was reading an article about the electron orbitals of iron and copper: The electronic configuration of iron is 1s 2, 2s 2, 2p 6, 3s 2, 3p 6, 4s 2, 3d 6 And that of copper is 1s 2, 2s 2, 2p 6, 3s 2, 3p 6, 4s 1, 3d 10 Iron has an incompletely filled d orbital while copper has a full...

    Copper's Valence Electrons: How Can It Lose More Than One?

    Copper has one valence electron, but it can lose more than one when forming cupric compounds. I had thought it could only lose the valence electron. How can this happen? If this is true, how does an electron from the d orbital jump to a higher orbital if only valence electrons can make the jump?

    Free radical polymerization

    Does branching occur during free radical polymerization of ethylene even at high temperatures and pressure or only on other type of monomers using free radical polymerization at lower temperatures? I was reading this article: http://en.wikipedia.org/wiki/Polymerization It was not very...

    BCS Theory Magnetic Flux Question

    From Wikipedia: "An electron moving through a conductor will attract nearby positive charges in the lattice. This deformation of the lattice causes another electron, with opposite spin, to move into the region of higher positive charge density. The two electrons then become correlated. Because...

    BCS Theory Magnetic Flux Question

    So the flux gets quantized because all the spins align? I know that electrons are in specific orbits because of their wave function (I believe I am using this correctly). So they can only occupy certain states. They cancel out in other states; De Broglie. What is it about atoms that causes...

    BCS Theory Magnetic Flux Question

    In superconductors, electrons form Cooper pairs that move at the same speed. Also, magnetic flux becomes quantized. Can someone explain in layman's terms why and how the magnetic flux becomes quantized? Especially in contrast to the magnetic flux in a conductor. Does it have something to do with...
