It is because a a shell can occupy only a maximum of 8 electrons which satisfies the octet rule.\n\n the rules are:\nHUND's rule of maximum multiplicity\nPAULI's exclusion principle\nAUFBAU principle

It all comes down to two forces: the attraction between electrons and the nucleaus and the repulsion between the individual electrons.  This leads to a complex set of equations that do not have a solution. \n\nIf we assume that molecules behave as a combination of atomic states of only one electron, then we can try to formulate solutions of the equations (because the electron-electron repulsion term is zero). \n\nUnfortunately, the equations do not have a single answer. They have multiple answers. These answers have been called electronic configurations and are your different shells, sub-shells, etc. The actual quantum numbers are seen in the equations as solutions to the Schroedinger equation(HY=EY): n, l, ml, and ms.\n\nThe prevailing intepretation are that these states are energy levels which can be occupied by electrons as the form molecular bonds. \n\nMy university professor would probably remove my liver for such a poor description of the phenomenon, but this was always my best understanding of it.

Question:  Exactly how fast do electrons travel?\n------------------------------------------------\nAnswer:  Electrons can have a wide range of speeds.  A slow case: we know that\nelectrons move when there is a current flow in a wire, but the speed at\nwhich the electrons themselves move in the wire -- the so-called electron\ndrift velocity -- surprises most people.  For example, for a copper wire of\nradius 1 mm carrying a steady current of 10 amps, the drift velocity is\nonly about 0.024 cm/sec ! On the fast side: the Bohr model of the hydrogen\natom has the (bound) electron zipping around the nucleus at about 2 million\nmeters/sec.  And on the very fast side, some examples are: beta particles,\nwhich are emitted by some radioactive materials; and the innermost elec-\ntrons of atoms of elements having large atomic number, such as uranium.  In\nthese cases the electrons are traveling at very nearly the speed of light.\n(about 300 million meters/sec).\nRcwinther

You apparently know what the diagonal rule looks like, but the link below gives a quite nice picture of it.\n\nBasically it is a summary of the order in which electron shells will be filled up. Follow the arrows round to discover where the electrons will go, starting at the 1s level.\n\nSo for 15:\n2 electrons will go into 1s, filling that up\n1s2\nthe next electrons will go into 2s2, 2p6, 3s2 and then the remaining 3 electrons into the 3p orbital, giving us a structure of:\n1s2 2s2 2p6 3s2 3p3\nRemeber, on your diagram, the first two characters (2p, 4d etc) are the names of the orbital, and the final digit is the number of electrons in that orbital. On your diagram the final digit shows the maximum number of electrons on the orbital; when you write out the structure the first few orbitals will be full (1s2 2s2 2p6 3s2) and the last one will be part full of however many electrons you have left (3p3.)

Yes,It was proved that  the electron can't be restricted to a space as small as an atomic nucleus. The process you describe doesn't involve confinement of an electron. It involves a transformation of an electron (and a proton) into a neutron. If the electron retained its identity as an electron, after the transformation- then there would be a problem.\n\nThe capture of s electrons by a proton occurs within an unstable, neutron-rich nucleus. Usually it's the 1s electrons that are captured. When a vacancy opens up in the 1s orbital, an electron from a higher shell drops into its place, dumping energy as X-rays. The X-rays are experimental evidence that electron capture by the nucleus is taking place. Luis Walter Alvarez was the first to demonstrate nuclear decay via K-shell capture in 1937 (just a year out of grad school).\n\nAnything that affects the 1s electrons could affect the electron capture rate. Since the 1s electrons can be perturbed slightly by valence shell events, it's reasonable to expect that you'd have a rare instance of a nuclear reaction that can be influenced by a chemical reaction. I'd also expect the coupling between the two to be pretty weak, because the 1s electrons are really not very sensitive to chemistry.\n\nOn this very question you have asked, with this explanation, many aspects of Quantum theory are surviving.Goodluck and Peace<3

No electron path. If this was true electrons would have eventually collapsed into the nucleus

positive or negative charge... depending on how tightly they hold their electrons

It's a Chemical/Fusion reaction...

,Good made me think.  The same, I guess in the end your just exchanging electrons.  However, the impulse in the brain will not fire until a certain discharge potential is met.  Also there are moderators in the synapse gap that can slow down the current exchange.  Serotonin is one.

They are just one electron away from achieving an octet.  So they require lower energy to lose this electron in a reaction.

for example:\n\nCl-1: has 18 electrons = 17+1\nif u are talking about simple configuration: then ok:\nelectron config: 2,8,8\n\nif u want the SPDF configuration: then:\n1s2 2s2 2p6 3s2 3p6

This is a more complicated question than it appears.  You didn't include to what degree you were seeking this information, so rather than go into a great deal of explanation I have included a link that explains and tabulates the basics of electron energy levels.  Hope this helps.

Break this up into three questions to Yahoo Answers:\n\n1. What is the charge e of an electron?\n\n2. What is the mass m of an electron?\n\nand after those are answered,\n\n3. What is [...] divided by [...]?\n\nYou can "spend" more points that way. :-) :-)\n\np.s. And the answer is: The e/m ratio of an electron is a constant of nature the numerical value of which depends on the units used.
