Honors Chemistry Chapter 3-4 Test Study Guide
There are 85 points possible but I will count it out of 80.
Chapter 3 (33 points)
1) If 6.0g of element K combine with 17g of element L, how many grams of element K combine
with 85g of element L? (30g) This is an example of the Law of Definite Proportions. (1 pt)
2) Define the Law of Multiple Proportions and the Law of Conservation of mass. (2 pts)
3) Understand the Cathode Ray tube experiment (electrical current-cathode end and anode end,
gas under low pressure, production of a cathode ray and what it is made of) and the Gold Foil
Experiment (atoms found in every substance were mostly empty space…with a small, dense
positively charged part called a nucleus) (6 pts)
4) Define the following: neutron, proton, electron, isotope (1 pt)
5) As the mass number of an element’s isotopes increase, what happens to the numbers of
electrons, protons and neutrons, assuming the atom stays neutral? (1 pt)
6) The number of atoms in one mole of ANY substance is__________________. This is called
_______________________number. (2 pt)
7) Phosphorus-33 (atomic number 15) contains how many protons, neutrons and electrons? (1 pt)
8) Matching of the following scientists and their discovery: Aristotle, Dalton, Democritus,
Millikin, Rutherford-Marsden-Geiger, Thomson (6 pts)
9) Know the 5 parts of Dalton’s Atomic Theory and what 2 parts have changed in the modern
atomic theory. (2pts)
10) Understand the following terms and their relationships….short answer worth 3 pts: atomic
structure, atomic number, mass number, isotopes, average atomic mass.
11) Complete 3 problems: (one of these requires two equations and one is multiple choice!!!)
# of moles to mass in grams and vice versa (4 pts)
mass in grams to number of atoms and vice versa (3pts)
12) Be able to explain how to calculate average atomic mass. (1 pt)
Chapter 4 (52 points)
