1. What are the properties that make noble gasses unique?
2. What are periods? What are groups/families?
3. What are the SI units for measurement (mass, volume, density, length)?
4. What are the symbols for the units of measurement? Which are smallest/largest?
5. How do you calculate density?
6. CONVERSIONS / DIMENSIONAL ANALYSIS!!
7. How do you determine the number of significant figures present in a given number?
(with decimal, without decimal)
8. How many significant figures can you have in an answer? How do you know?
9. What is the law of definite proportions?
10. What is the law of conservation of mass?
11. What are the postulates of Dalton’s atomic theory? Which are still correct? Which
have been proven to be incorrect?
12. What is the relationship between atomic number, mass number, number of protons,
number of neutrons, and number of electrons?
13. What is an isotope? How do you determine number of protons/neutrons in an
isotope?
14. How do you find the mass of a given number of moles of an element?
15. What does it mean for an electron to be in the ground state? Excited state? How do
these, and the movement between them, correspond to energy (either absorbed or
lost)?
16. How many electrons are in an orbital? How many orbitals are in each sublevel? What
are the sublevels? What are the principal energy levels?
17. What are alkali metals? Alkaline earth metals? Halogens? Noble gasses?
18. How is the periodic table set up? What do elements in the same family/group have in
common?

sublevels? s? p? d? f?
20. What is the most reactive group of nonmetals?
21. What is ionization energy?
22. How do you find the atomic radius of an atom?
23. How many electrons do the diatomic halogens have in their outer shells when they
make non-polar covalent bonds with themselves?
24. Can you draw a simple Lewis structure? NaCl? HCl? H2O?
25. You still have to be able to name ionic compounds.
26. Can you figure out a percent composition of a compound? % = part/whole
27. How do you find an empirical formula? What’s the jingle? % to mass…
28. How do you find a molecular formula? They are based on mass…
29. What is a precipitate?

31. Can you balance an equation?
32. ionic compound Formula  Name           Name  Formula
33. acids Formula  Name        Name  Formula
34. hydrates Formula  Name        Name  Formula.
35. What was Rutherford’s experiment? What were its conclusions?
36. What is molar mass?
37. What does Aufbau’s principle state?
38. You must know your lab equipment!
39. You must be able to read lab equipment to the correct decimal!
40. Molecular compounds Formula  Name          Name  Formula
41. How do you find the average atomic mass given isotopes and percentages?
42. Why do scientists have international standards?
43. Name molecular compound and write their formula from the name.
