PART A (5 points)
Use the Periodic Table of the Elements (page 917 in your book) to answer the following
questions. You need to answer every question correctly to receive credit for this assignment
so work carefully.
1. Which element has the chemical symbol “As”?
2. What is the average atomic mass of the element in Question 1, rounded off to the nearest whole number?
3. How many protons does the element in Question 1 have?
4. How many electrons does the element in Question 1 have?
5. How many neutrons does the element in Question 1 have?
6. Add Questions 3 through 5 together. What do you get?
7. Name the element that has an average atomic mass that is equal to your result in Question 6.
8. What is the chemical symbol for the element you got for Question 7?
9. For the symbol you got in Question 8, change the letter “g” to letter “u”. What element and chemical symbol
to you have now?
10. What is the atomic number for the element you got in Question 9?
11. Subtract 20 from your answer to Question 10 and record the new number here.
12. What is the name of the element that has an atomic number that matches your answer to Question 11?
13. What is the chemical symbol for the element you got in Question 12?
14. For the symbol you got in Question 13, change the letter “r” to letter “t”. What element and chemical symbol
to you have now?
15. How many protons do atoms from the answer to Question 14 have?

16. Subtract 68 from your answer to Question 15 and record your new number here.
17. What is the name of the element that has the same atomic number as the number in Question 16?
18. How many neutrons does the element in Question 17 have?
19. What other element (besides the one you named in Question 17) also has the same number of neutrons
you answered in Question 18?
20. What is the atomic number for the element you got in Question 19?
21. What do you get when you divide your answer to Question 20 by 9?
22. What is the name and symbol for the element that has an atomic mass equal to your answer for Question
21?
23. How many protons does the element in Question 22 have?
24. How many neutrons does the element in Question 22 have?
25. Add 33 to your answer to Question 24 and record the new number here.
26. Which element has the same atomic number as your answer to Question 25?
27. What is the chemical symbol for the element in Question 26?
