Hybridization [ENDORSED]

what would the hybridization of Xe be in XeF4 ? I'm confused as to how to figure this out since the central atom has two regions of electron density

Re: Lewis Structure and Molecular Shape

No valence electrons are the only electrons that participate in bonding and therefore determine the overall molecular shape

Re: Formal charge purpose

Instead of calculating the formal charge, could one simply make sure that all the atoms have the correct number of valence electrons ? or would this not work all the time?

Ionization exceptions [ENDORSED]

Will we need to know the ionization exceptions for the midterm? Such as Oxygen has a lower ionization energy than Nitrogen even though it is to the right of Nitrogen?

3d before 4s

Is it correct to say that as soon as the 3d orbital has at least one electron you write it before the 4s orbital except for Cr and Cu?

Re: Homework 2.43 [ENDORSED]

Regarding this same question, I thought the electron configuration for silver (Ag) would be [Kr] 5s^2 4d^9 but the solutions manual has the answer as [Kr]4d^10 5s^1. Why does the 4d come before the 5s?

Could someone please explain how to do this? Use the above uncertainty in velocity to calculate the electron's uncertainty in kinetic energy. Then calculate the uncertainty in kinetic energy per mole of electrons(that is, per mole of hydrogen atoms).Comment on your value. (delta v= 3.4*10^10 m.s). I...

In the solutions manual to this question it shows the calculation of obtaining the moles of 2NH3 as 35.0g/17.031g. I was a bit confused on why 17.031 was being used, isn't the molar mass of 2NH3 31.038g.mol-1?
