Electron Configuration &
Exam Preparation Check-up


This assignment is past due and can no longer be submitted.


Look at chapter 3 in your textbook, especially sections 3.7 and 3.8, for help with this assignment. In addition to practicing electron configurations, this assignment includes an exam preparation check-up to help you gauge your preparation for our first exam on Wednesday, February 11.


Electron Configuration

1. What is the maximum number of electrons that can be found in a single p orbital?
   
2. How many electrons are needed to fill all the 3p orbitals?
   
3. Order the following orbitals from lowest to highest energy:
4p, 3s, 2p, 3d, 4s.
(Hint, you should be able to do this using the periodic table.)
Your answer would look like 1s < 2s < 2p, etc.
 
   
4. What neutral element has the following electron configuration?
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2
   
5.

What neutral element is represented by the following electron configuration?

6. Write out the electron configuration of a neutral scandium atom. You can type 1s2 2s2 2p1 as 1s^2 2s^2 2p^1 etc.
 
   
7.
a. What is the electron configuration of S2- (HINT: How many protons does sulfur have? How many electrons would it have when it has a 2- charge? Now write the electron configuration for S2- using that number of electrons.)
 
   
b. What neutral element has the same electron configuration as S2- that you just wrote above?
 
   
c. What alkali metal with a +1 charge has this electron configuration too?
   
 

 


Exam Preparation Check-up

The following is a list of activities that a student would do to be maximally prepared. How are you doing? We are asking these questions to help you assess your progress. You might think of this as a "to do list" of tasks you can do to prepare for the exam. You will not be "graded" on your honest answers to the next set of questions.

1. How often have you been reviewing your lecture notes?
  After every lecture (best answer)
  Every week
  Just started this weekend
  Never

 

2. How often have you been working through the examples and the problems within each chapter of the text? (For example, on page 57 in your text, Worked Example 3.6, Problem 3.16 & 3.17)
  After every lecture (best answer)
  Every week
  Just started this weekend
  Never

 

3.

Specifically, which homework questions have you done?

Chapter 1: 14, 18, 23, 25, 28, 31, 37, 41, 44, 48, 50, 58

all 75% 50% 25% none


Chapter 2a: 36, 39, 41, 42, 44, 46, 47, 96
Chapter 2b: 12, 49, 53, 56, 59, 61, 63, 64, 66, 69, 72, 86, 87b

all 75% 50% 25% none


Chapter 3a: 26, 35, 38, 42, 44, 47, 50, 61, 63, 100, 101
Chapter 3b: 31, 66, 68, 71, 73, 77, 78, 84, 102

all 75% 50% 25% none

 

4. Have you looked at the old exams?
  Yes, I worked out answers to all the questions. (best answer)
  Yes, I read through the questions.
  Not yet, but I plan to work out answers to all the questions.
  No.

Both Mr. Anliker and Dr. De Amicis hope your studying is going smoothly so that you are well prepared for the exam.
