  1. Will the energy gap between the n=1 and n= 3 orbitals be the same in different elements? For example, will the n=1 to n=3 energy gap in hydrogen be equal to that of helium? (it isn't right?)
  2. why is energy liberated when the bond is broken?
  3. When ATP is converted to ADP one bond is broken and a phosphate group is liberated. But shouldn't energy be put in to the molecule to break a bond? If that's the case, how does breaking the phosphate bond allow ATP to give energy to other molecules?
  4. For hybridization to occur, must electron always be promoted? Is it possible for hybridization to occur without the promotion of an electron? Secondly, if electrons DO need to be promoted, must there be at least one completely empty orbital in the shell it is being promoted to? For example, say an electron is promoted from 2s to one of the 2p orbitals. What if every 2p orbital already had 1 electron? (a configuration such as [math]{2s}^{2},{2p}^{3}[/math]). Would an electron still be promoted to one of the p orbitals to make a configuration like [math]{2s}^{1},{2p}^{4}[/math].. (my problem lies in the fact that after promotion (if it does occur) that there will be two electrons in a one of the p orbitals... Can that happen in when electrons are promoted?
  5. What is the difference between VB theory and Molecular orbital theory? Tutorials on valence bond theory state that the orbitals of the individual atoms overlap when a bond forms. Doesn't that also form a molecular orbital? if so what is molecular orbital theory?
  6. ah... thanks for your help , everyone! I guess I though I posted it because of the "007" part in out usernames.
  7. Whoops... In my rush to make this post I obviously made a typo.. Yeah I meant Zinc is more reactive than Fe Merged post follows: Consecutive posts merged I'm guessing that since it's the 4s orbitals that take part in reactions, the effects of the shielding of the 3d electrons comes into play. Since the shielding effect of the electrons in zinc is greater it can involve it 4s electron in reaction more easily. Am I right?
  8. thanks for trying... I was looking for info on the actual electronic configuration (1s2 2s2 etc)
  9. Can you explain why zinc reacts with oxygen more readily than iron because of it's electronic configuration? EDIT: If you want to check the electronic config of both metals search google for "dynamic periodic table" and follow the first link.
  10. I think understanding what "quasi free" electrons are is quite beyond me.. ;-) So.. basically it's not electron jumping up and down in the energy levels that causes black body radiation but the vibrational energy of atoms right?
  11. but what are the two particles which are colliding? is it two adjacent nuclei?
  12. what do you mean by "acceleration of charges during collisions"?
  13. How is light reflected off a particular material at atomic level? And how does that relate to blackbody radiation?
