Iron has two common charges, +2 and +3, justify each of these charges using the orbital notation of the neutral atoms.

It has plus 2 charges because its protons are charged. The same with 3 plus protons.
So you have a up and down on the chart.
I'm in business and never have to take that crap. I even took AP Chemistry back in the days but I had a job in high school so I bought my classmates lunch for doing my homework.

Nobody ask you for your life/lie stories:lol
Jameer im going to see if i can help you. I took chemistry in college but that was like 8 years ago and it was in Spanish :lol
Going to look for info.

Fe 2+ would be: 1s2 2s2 2p6 3s2 3p6 3d6 while fe +3 would be the1s2 2s2 2p6 3s2 3p6 3d5.

is that what they mean by 'justify'?
Bandito
02-13-2014, 09:44 PM
I think so yes. There is one less electron in the orbital configuration due to the fe2+ losing an electron and becoming fe 3+. Fe 3+ loses one little arrow in the 3d orbital. The one i uploaded is for fe 2+.

Iron has two common charges, +2 and +3, justify each of these charges using the orbital notation of the neutral atoms.
Iron's electron configuration is [Ar] 3d6 4s2 so it's valence shell (the outermost subshell, in this case the 4s subshell) is 4s2 in ground state ("neutral").
http://images.tutorvista.com/cms/images/49/iron%20electronic%20configuration.jpg
Remember that orbitals "like" (are stable) to be completely filled or exactly half filled. Iron +2 means you take away 2 electrons from the figure above, and it is stable because then the 4S subshell will be empty. You can see that the first of the "d" orbitals still has 2 electrons, though. So if you were to remove one additional electron (now you have taken away 3 electrons total and have Iron +3), the d orbital is exactly half filled and is stable.
*in reality if you remove the two 4S electrons for the +2 configuration, the first pair in the 3d orbital will actually donate a single electron to the 4s orbital, so there is exactly one electron in each 4s and 3d orbital (all of them are exactly half filled, so it is stable). Then the +3 will take away that single 4s orbital electron, leaving exactly 1 electron in each 3d orbital (so 5 in total). But don't worry about that unless your teacher has gone over that/clearly stated they expect you to know that, which I highly doubt.

The real answer in conjunction with the orbital notation and electron bookkeeping mentioned earlier is iron's nearest noble gas configurations are too far away. Even though the octet or the ground state is the lowest energy that iron can form(orabbus made a mistake, transition metals include multiple subshells in its valence; in iron's case both the d and s subshell are included in its valence), there are other low states of energy iron can take. These Fe 2+ and Fe 3+ cations form because it takes less energy to lose 2 or 3 electrons then to gain 8 or 10 electrons. Now which form is likely to exist depends on other factors like nearby electron sinks and sources, temperature, etc.

To all you morons telling little Jameer the answers to his little Science problem. DO YOU REALLY THINK TELLING HIM THE ANSWERS WILL HELP HIM SUCCEED IN THE LONG RUN!!?? Think about it, All you're doing is giving him the answers instead of letting him be a man, and figure it out himself. I for one knew the answer to this but decided not to give it why? Because I care about Jameer, he needs to face these kinds of problems ALONE or he'll never grow into a real man

You are right, but let's be real. What's the first thing anyone does in college when they have a chemistry/math/physics problem? If it's not in the back of the book they google it or look for a site that has the answer :lol
There's always the possibility he will blindly copy the answer without thinking about why it is the answer. Hopefully though, seeing the answer to this one problem will help tie some concepts together, and make him think about this problem. plus I'm sure he has other hw problems.
Had he scanned his HW or asked like 5 questions, I wouldn't have answered. Since he only asked one single question I'm hoping he has the rest of it done and just needed this last one to complete it. If that's not the case the other guys and me are def not helping though haha

Good catch, why is that again? Is it just because they are so similar in energy it's equally likely to remove an electron from either subshell?

This shit seems easy compared to second term gen chem. We're doing calculations for enthalpy change in reactions. It gets really confusing trying visualize whether the system is absorbing or losing energy.
I didn't know that water has a different boiling point depending on elevation. For example the boiling point of water in Denver is lower than a city at sea level.
I also just learned that when a solid (like ice) is transitioning for a solid to a liquid the temperature of the solid doesn't change. It's the same until it is completely liquefied. Only then can the substance increase in temperature. Chemistry is a fascinating subject.

Remember that altitude changes pressure which pretty much changes everything.

Yeah, boiling is essentially when vapor pressure = atmospheric pressure so boiling point changes when you change altitude due to pressure changes.
