AP Chemistry Question of the Day --49

Welcome back to my blog. Here comes the answer to question 48 I posted earlier. The correct answer is C. 

Inner electrons shield outer electrons more efficiently. As a result, the lower the principle quantum number, the closer the electron is to the nucleus,  the less screening the electron feels and the higher the effective nuclear charge. Among the four choices, C is correct. 1p orbital does not exist. comparing 2s and 2p, 2s has lower energy than 2p.


Following is Question 49 of the series. 

49. What is the solubility of lead (II) bromide at 298K if Ksp of lead (II) bromide is 6.6x10-6?

I will post the answer and explanation tomorrow.
