How is the electron able to jump through the nucleus in a p orbital?

Why does iron exhibit only a 2 and 3 oxidation states?

Iron have 2+ charge or is ionic because it is very easy to lose an electron from the 4s orbital. 1s22s22p63s23p64s23d6 is the electronic configuration of iron, the fourth orbital 4s even though is filed first than the 3p orbital; will lose its electron first as it is the outermost orbital. Electrons wil be lost first from 4th, 3rd, 2nd 1st orbital like that but will not necessary be able to lose all its electrons, ok....- Athlaa

What change to the nucleus when it loses one electron?

Just making sure, first off, that you realize electrons are not in the nucleus. They float in the empty space around the nucleus, of an atom. But if your asking what happens to the atom once it loses an electron, the atom then has a positive charge, and becomes a positive ion. The atomic size[of the atom alone] becomes smaller due to the greater pull the protons are able to have on the electrons.

What does the Bohr model of argon look like?

argon is odorless, colorless, pratically invisible....

Why wouldn't you be able to see a nucleus through a microscope?

Assuming there actually is a nucleus in the cell (it isn't undergoing cell division or anything), the nucleus is actually transparent and you see it with dyes that target it. You might be able to see it if it isn't transcriptionally active, when the DNA is condensed inside it.

What part of a atom causes particles to bounce back?

The heavy, dense nucleus of the atom caused the alpha particles to bounce back in Rutherford's experiment.

What element group is considered to be an electron donor?

metals.this is because metals contain "free electrons" in thier outermost shells which are weakly held by the nucleus. so they are able to donate electrons

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

Do animals have a cell nucleus?

Yes, they have a nucleus. Without a nucleus, cells wouldn't be able to function, and that means we wouldn't be able to function, which means all animals would be dead if their cells didn't have a nucleus. The only animal cell without a nucleus is the red blood cell.

How did Einstein prove the existence of atoms?

Einstein did not prove the existence of atoms. This was done by Ernst Rutherford at McGill university using X-rays shot through a piece of gold foil. He found that X-rays were able to pass through a piece of thin gold foil, but that they were scattered in some instances. By doing this, he elucidated the subatomic structure of the atom as a nucleus surrounded by an electron cloud.

Why only transition elements are known to form pi-complexes?

Bonding in π-complexes is strongest when both the filled π-bonding orbital of the π-bonded ligand donates TO the metal and the empty π* orbital on the ligand can accept electron density FROM the metal. A metal with a partially-filled set of d orbitals is able to participate in this synergistic mode of bonding; main group atoms virtually never have filled pπ orbitals available for donating electron density to π-complexed ligand, hence this kind of complex occurs only with transition metals.

Why do electrons move in shells?

AnswerIn fact, electrons do leave their shells. Around atoms they only exist in shells (quantum energy states) but can change energy states by moving from one shell to another. They can also completely leave one atom and take up residence with another or even remain free. This is the nature of electricity. If electrons were permanently bound to the shells on one atom, out lights and computers simply wouldn't work. AnswerThe question wording needs some clarification. There are two issues of concern here - the electron spin, and the "orbit" around the nucleus. These will be addressed separately. Electron SpinIn the classical sense, the electron was once considered to spin about its axis in the same way the earth rotates around its axis. Classical mechanics yields to quantum physics here, because the electron does not actually spin about its axis in the same the earth does. Instead, we measure the angular momentum of the electron, which is a quantum factor.The spin of an electron is always 1/2, and can be measured and confirmed experimentally. This value is constant (although it can be said to be "up" or "down"). The scalar value of the electron spin never changes from 1/2.Electron OrbitalsAn electron travels around the nucleus in confined quantum regions, or shells. Unlike a planet that orbits the sun in a predictable elliptical orbit, an electron's trajectory within its shell is random and unpredictable. Consider a spherical cloud around the nucleus. That cloud is made up of one or two electrons, and there is a known probability that you will find an electron on any point on the surface of that shell.As a thought experiment, if you were able to take a video of a single hydrogen atom, you would observe the nucleus at the center comprising one proton (and one neutron in deuterium), surrounded by a distant, thin opaque sphere. The sphere is not solid, it is just a single electron buzzing around the nucleus so quickly that, in the time your camera had a chance to register one frame of the image, the electron had buzzed all around the nucleus so many times that the sphere appears to you to be semi-solid.By strict definition, only two electrons can occupy the same shell at one time, due to a phenomenon called the Pauli Exclusion Principle. In many atoms, several shells have exactly the same energy levels, and so in quantum parlance we combine shells of identical energy levels together, and consider them as a single shell. There are n2 shells with identical energy levels for each orbital number, so therefore there is 1 shell for the first orbital, 4 shells for the second orbital, 9 shells for the third orbital, and so one. Since each shell can contain no more that 2 electrons, there are 2 electrons allowed in the first orbital, 8 in the second, 18 in the third, and so on.AnswerThe nucleus carries a positive charge and the electron carries a negative charge. Better answers are more complicated, but this should be a start.[This answer is incorrect - spin has nothing to do with charge]More informationWhen we talk about electron spin, lots of folks get the impression that electrons "rotate" about an "axis" in the same way the earth does to make day and night. It's not really like that. Spin is actually a quantum mechanical characteristic rather than a "physical spin" like the revolution of planetary bodies. Hey, we assign color as a quantum mechanical characteristic, but that doesn't mean that what we assign a color to actually has "color" or is a certain "color" as in being possessed of a certain hue.
