Asked by Daniella O - Fri May 9 22:06:04 2008 - - 2 Answers - 0 Comments

A. The easiest way to answer this type of question is to look at a periodic table. Recall that it is organized according to electronic configuration, with the first two columns correspond to the s orbitals, the next ten to the d orbitals, and the last six to the p orbitals. Aluminum is in group IIIA, so it has three valence electrons. The first two are in the s-block, and are thus paired up. The last one is in the p-block, and is unpaired. However, an aluminum atom stripped of 3 electrons (e.g. Al3+) is left with no valence electrons at all--only the electrons in the filled, lower-energy shells. Chlorine is in group VIIA, so it has seven valence electrons. The first two are in the s-block, so they're paired off. The other five are in the p- [cont.]

How many unpaired electrons are in one sulfide ion in the ground state?
Q. I know the answer is 0, but I don't know why? Can someone please explain why to me? Is it because there are 6 electrons in the sulfide ion, thus there are 0 unpaired electrons? This is the same problem, but I don't know the answer to this one. How many electrons are in the 3d orbital of a titanium atom in the ground state? Would the answer be 4? Any tips? Please help!

A. Mn is in 7th (VIIB) group. Its electron configuration is [Ar]4s2 3d5. Since the 2 s-electrons are paired, and since the 5 3d-electrons like to ocupy as many d-orbitals as possible, The number of unpaired electrons in Mn is: 5

Need help how to figure this problem out about unpaired electrons?
Q. How many unpaired electrons are there in a chromium atom? I know I have to do something with Hund's rule but I can't figure this out. Thanks for your help!
Asked by duck_michelle - Mon Jun 25 19:08:30 2007 - - 1 Answers - 0 Comments

A. There are 24 electrons in a chromium atom. The first two are paired on the first level (s level). There are three "p" shells that will hold a total of 6 electrons (two each). 2+6= 8, which means there are 16 electrons left. 10 of these are on one of five "d" orbitals, which each hold 2 electrons, and the last six are on an "f" orbital, which can hold up to 14 electrons in its seven orbitals. The information on the "f" orbital is what you really need. Hund's law states that no electron will share an orbital if there's room for it to have its own. Since there are seven orbitals and only six electrons, each of the last six electrons is unpaired. Hope this helps!

Asked by FalennixonX - Fri Jan 20 10:06:31 2006 - - 1 Answers - 0 Comments

A. Here, this question asks you for three things: Bond order, unpaired electron, and whether each is paramagnetic or diamagnetic. I figure that you already know what molecular orbital model is? Right? If you do, this problem is very very easy to approach. Look in your text book or google it for more info. Anways, I'll list the asnwer like this: --Bond Order:--Unpaired electron:--Dia-/Para: F2+ has 1.5; 1; P F2 has 1; 0; D F2- has 0; 1; P Remember the + means there is one less electron and - means there's one more. Also, I'm doing the Bond Order in my head so check again to make sure. Ask me any question regarding on this problem. It's very simple so I don't think you have much problem here.

A. Chromium is an exception to the Aufbau principle (which tells us how electrons are added to the orbitals). In order have a more stable half-filled d-sublevel, an electron moves from the 4s to an empty orbital in the 3d to give five unpaired electrons in the 3d and 1 unpaired electron in the 4s. This will be lower in energy, and therefore more stable, than [Ar]4s2, 3d4. The most stable electron arrangements are as follows, starting with the most stable: 1. Inert gas configuration 2. Completely filled sublevel 3. Half-filled sublevel The same thing happens with copper. An electron moves from the 4s to the 3d (originally with 9 electrons) to give a filled d-sublevel and 1 electron in the 4s. That is why copper is in group IB. The… [cont.]
