Mastering Chemistry assignments

I am getting the same question over and over again on the blog and by email, in addition to addressing it explicitly multiple times in class. Here is the answer again: the ONLY graded assignments are the graded quizzes. Their due dates are as follows:

Graded Quiz 1 - Chapter 1.1, 1.2, 1.3 – Due Wednesday September 18 
Graded Quiz 2 - Chapter 1.4 to 1.9 – Due Wednesday September 25
Graded Quiz 3 - Chapter 2 (all) – Due Wednesday October 9
Graded Quiz 4 - Chapter 3 (all) – Due Wednesday October 23
Graded Quiz 5 - Chapter 4.1 to 4.5 – Due Wednesday October 30
Graded Quiz 6 - Chapter 4.6 to 4.8 & Chapter 5 – Due Wednesday November 6
Graded Quiz 7 - Chapter 6 (all) – Due Wednesday November 27
Graded Quiz 8 - Chapter 7 (all) – Due Wednesday December 4

(taken directly from the course website).
EVERYTHING else is simply for practice, and is entirely optional and for your benefit only. Assigned homework will be reassigned at a later date so you can try it again for revision purposes.

What is the fastest way of doing this question:

Calculate the wavelength of the radiation released when an electron moves from n= 5 to n=2

I have a question for Homework Assignment 1. When it asks for the condensed electron configuration, why is the answer [Rn]7s^25f^36d^1 and not [Rn]7s^25f^4? Can you please explain this

I understand that the assignments are not for marks, but could you please change the due date of assignment 1? I want to do the problems to practice for the quiz on Wednesday, but we have not yet covered all of the material in class. This assignment closes tonight, so we will not be able to practice the questions after we learn the material in class tomorrow.

351: use the equation 1/lamda = R(1/2^2 - 1/5^2)
828: U is anomalous. You'd only get it right if you looked up the correct answer. Don't worry about it.
909: I will pass on your request to Dr Briggs.
