Knowing Avogadro's number explain why the sky is blue.

What is the electronegativity of Neon?

In the night sky is black!
Seriously - there is no correlation

What is the electronegativity of Neon?
Which scale?

Well, you can use Avogadro's Number and the percent composition of air to determine the molar composition of standard air.  From this you can calculate the wavelengths of light absorbed and reflected in our atmosphere and determine which wavelengths are the most visible.  Due to the very high quantity of Nitrogen in our atmosphere, our sky appears to be blue.  During sunset and sunrise, the angle of the sun is close to the horizon where a greater quantity of CO2 exists causing the sky to take on a reddish tinge.  On Mars, the sky is red since its atmosphere is almost entirely carbon dioxide.

These questions are just some I'm starting to collect. I'm not sure there is any right answer, mostly the committee just wants to see how you begin to approach the problem.

Most of the staff are PhD students. But others are lecturers, undergrads and a few high school students.

I am not a PhD student.  I just have a B.S. in Forensic Chemistry and a strong interest in chemistry.  (As can be seen by my collection of elements).

Well, many people have said that I have an "odd" sense of humor and a very unique personality.  My past is riddled with very humorous and sometimes stupid stories.  The quote comes from a website that I frequently visit because it insults and attacks anything and everything.  The quote just made me laugh uncontrollably.  Also, I believe that if you cannot laugh at a fart joke, then you have become old.  The day that I find a fart joke to be not funny is the day that life has passed me by.   ;D
