sigma and Pi bonds

I'm still a bit confused about these two. Can some give a quick sentence in the major difference of the two? Thanks in advanced.

Hemoglobin Structure

In class we just went over that 4 proteins form together to form hemoglobin, do we need to know how the 4 protein form together?

Lone Pairs

I know that when we have lone pairs the 3-D shape changes, however does Hybridization change as well due to have lone pairs instead of bonds?

Chemical Formulas (test 3)

For the test, do we need to know how to translate the names of chemical formulas. Or will the chemical formulas be given?
Ex. Magnesium Arsenide is As2Mg3, or will As2Mg3 be given

Re: Isoelectronic atoms and their relative electronegativities

If im reading your question right, then i believe that their electronegativities are subject to change if they lose or gain an e. if they gain an e, it's easy for them to lose and if they lose an e than they are more likely to gain an e. Therefore their electronegativities change

Does helium follow the electronegative trend of the periodic table or is it an exception to rule becuase of how the table of elements is set up?

Valence shell on Noble gases

When looking at the noble gases, is it possible for them to gain anymore electrons even if their outermost shell is full? If so can they complete a new shell?

Re: electronegativity

The way that i remember this the easiest is by having electronegativity being at its lowest on the bottom left and the highest at the top right of the periodic table.

Re: Intensity of Photon

It is the amount of photons emitted in the experiment and it can be useful to know the work function or the Excess Energy emitted!

Re: Work Function

Work function can be given in Joules or as eV, however from the information given in the question we can find the work function. Work function is just the amount energy required to separate an electron from the metal.

Re: Balmer and Lyman Series

I think that we need to know the values that correspond to the Atomic spectrum so that we can Identify how different wavelengths result in different position on the spectrum like the series that you mention your question. So I think that we do need to memorize it.

Re: Rounding atomic weight (general question) [ENDORSED]

I think that best thing to do is to just follow the periodic table, that way you can't be wrong. Also it save time while performing in the exams.

Actually both can be used at the same time, the main thing is understand what each variable means, after understanding that you'll be able to see the relationships that are crossed over from both equations.

Re: moles to atoms [ENDORSED]

to convert you would need to multiply by Avogadro's number, because as you multiply you will cancel "mol" and be left with number of atoms for that mol.
