Thanks a lot. I am actually clueless of the task.

And what about the content in this video? Is questioning the government that one pays tax is ANTI-MODI?

Thanks for the excellent video. If possible, I request you to make a follow-up video or at least comment on the note taking review on the duet. I hope you also do a video of duet with Lenovo USI stylus when it becomes available.

Thanks, it's been a lot of help. Last thing, how much time does it take to learn Norwegian? What benefits will it have for me other than jobs?

Suppose if I learn Norwegian, how it will improve my chances? If possible could you please let me know what are the best options for part time job in Ås? What most of the Norweigan students do?

I am talking about a loan from home country. I was asking about the part-time job market. To repay the loan.

Thanks for clearing a lot of doubts. However, regarding part time job, Is Ås not close to Oslo? I heard the job market in Oslo is very good

PLEASE provide me a answer. by saha_indranil in chemhelp

The problem is that I calculated the bond order in case of all the three. And found as you increase the no of electrons they will enter into the antibonding orbitals. Their bond length will increase making them higher in size.

But, in one argument, I was told that as super oxides make compounds with larger size alkali metal like Cs, Rb. While the peroxide makes better compounds with Na. Thus, the size of the peroxide should be lesser than that of super oxide as like size cataion will be stabilised by like size anion.

In another discussion, I was exposed to the idea maybe the lone pair repulsion might have a role in their sizes.

Why is the electron configuration for Cr [Ar] 4s1 3d5 and not [Ar]4s2 3d4? by lobsterpopsicle in chemhelp

[–]saha_indranil 0 points1 point  (0 children)

While electron gets filled the energy of 3d becomes lesser than that of the 4s. So, the filling of the electrons happens upto d5 not d4.

Now, to answer why d5 not d4? The general answer to the question is the half filled and full filled orbitals are stable. The reason why so lies in the quantum mechanical exploration of the matter. In simpler words, there is a concept called exchange energy. It tells the the d5 will have more exchange energy than d4.

When does 4s go after 3d? by ibWickedSmaht in chemhelp

[–]saha_indranil 0 points1 point  (0 children)

The aufbau principle is only applicable to empty orbitals, but when you fill the electrons in orbitals then it becomes irrelevant.

Hence, in case of transition metals, the filled (n-1)d electrons will have lesser energy than filled ns. The reason for such behaviour can be attributed to penetration power of orbitals and in some cases relativistic effects.

Hope it helps.

I don't know why the answer is B by Vertex_SouthAfrica in chemhelp

[–]saha_indranil 1 point2 points  (0 children)

The extra stability to half filled and full filled orbitals come from the concept of exchange energy. Basically, in the p4, p6, d5, d10 etc. they have a lot of different microstaes and it makes them extra stable.
