  • Nickelocene Reactions, 3D Shape, Electron Count, Synthesis

    Please see the solution in the attached document. I think the main things to you look up to support these answers are the Jahn-Teller effect and Electron-Counts in organometallic compounds (18-electron rule).

  • Energy Shell

    Energy shells are filled according to the Aufbrau principle, until you get to 18. After which, the Madelung rule applies. At that point, electron filling is a bit more complex.

  • Working with schrodinger atomic model - Quantum states

    If m is the mass of the electron, from Newton's law we obtain Ze2/40r2 = mv2/r Using Bohr's angular momentum quantization rule for the value n, the Principal quantum number, we obtain both the velocity v, and the radius r as: v = Ze2/20hn

  • Lewis Formula and Molecular Bonding

    Are there any electron-dot formulas that you expect to give the best description? How would you describe the bonding in terms of electron-dot formulas? Answer) Structure II provides the best description since SeO2 has 18 valence electrons.

  • More effective than outer shell electrons in shielding

    Why is the energy diagram for multi electron atoms different from that of the hydrogen atom? The hydrogen atom consists only of one electron. Such electron interacts only with the proton in the nucleus.

  • Finding the Oxidation States of Elements

    Octet Rule: For the most part, elements want to have 8 valence electrons. This rule is known as the octet rule. The noble gases are unreactive because all of them have 8 valence electrons and the elements are stable.

  • Electron Properties: Distance, acceleration, collision, force, strength of electric field, point charge

    What acceleration must an electron have to gain 2.0 * 10^{ - 18} J of kinetic energy in this distance? 2) What force must act on the electron to give it that acceleration?

  • The Lewis Octet Rule

    Chloride, on the other hand, only needs 1 more electron to complete its octet, thus it will tend to form ionic compounds in which it gains 1 electron. Generally speaking, the Octet Rule doesn't tend to work out so well with larger atoms.

  • Lewis dot structure

    This solution explains in 253 words what a Lewis dot structure is and how to create it, referencing electron bonds between atoms, valence electrons, and the Octet rule.
