Atomic Structure

10. The nucleus takes up most of the room in the atom. True False Depends on the element Depends on the isotope Response Grid

11. The nucleus accounts for most of the mass of the atom. True False Depends on the element Depends on the isotope Response Grid

12. Electrons are about half the size of protons. True False Depends on the isotope Depends on the atom Response Grid

13. For an atom to be neutral, it must have the same number of _________. e- & p+ e- & no no & p+ e- & p+ & no Response Grid

14. According to the periodic table, what is the number “8” in the picture below? Atomic mass Atomic number Mass number Isotope number Response Grid

15. According to the periodic table, what is 15.9994 in the picture? Molar mass Mass number Average Atomic Mass All of the above Response Grid

16. What is the number “12” represent in the hyphen notation? Atomic number Number of protons Number of neutrons Mass number Carbon - 12 Response Grid

17. The top number is the _______ number while the bottom is the ________ number. Mass; atomic Atomic; Mass Neutron; proton Proton; neutron Response Grid

18. Which subatomic particle has to do with isotopes?

19. What is the mass of a neutron in amu?

20. List the # of neutrons, # protons, and # electrons for Calcium2+-42.

21. What is a negative ion called?

22. Name two isotopes.

23. Which isotope is all the element’s masses on the periodic table based upon?

24. If I have 2 isotopes, X-16 and Y-19 and my average atomic mass is 17amu. Which isotope is more abundant?

25. How many electrons are held in a d orbital?

26. How many orbitals are in a f sublevel?

27. How many electrons can be held in the 3rd energy level?

28. What does Hund’s Rule say? One electron can be added at a time. Each orbital must have 1 electron in the same sublevel before a 2nd electron can be placed in that orbital. Each orbital must contain one electron with an upward spin and one with a downward spin. There are only 2 electrons in each orbital.

You now have 1 minute for these questions 29. Write the electron configuration for Nitrogen.

30. How many valence electrons are in Nitrogen?

31. Write the box orbital notation for Sulfur.
