Quiz
• Know Table 1.5 on page 14
– Be able to convert back and forth
– 500 cm = ? m
– 500m = ? cm
• Know about intensive (do not depend on
amount) and extensive properties (depend
on quantity)
3
Quiz
• Know about the atom – how many protons,
neutrons, electrons in 37Cl
• Know meaning of:
–
–
–
–
Homogeneous mixtures (= solutions)
Heterogeneous mixtures
Physical change vs chemical change
Isotope
4
• Know the different experiments: Cathode
ray tube / oil drop / gold foil / study of 
and  particles:
– Who did them
– What they showed
5
Quiz
• Understand density
• In your calculations, keep track of your
units!
6
Name Game
• Know the names and formula of common
compounds. Especially study pages 61-64
• Given the symbol, know the name of the
common elements ( first 36, alkali metals,
alkaline earth metals, halogens, noble gases)
• Given the name, know the symbol
7
Atom
• Atomic number = number of protons =
number of electrons ( for element)
• Atomic mass + sum of number of protons +
number of neutrons
• Isotopes vary in number of neutrons
• 81Br has a mass of 81; atomic number = 35;
therefore 35 protons, 35 electrons; 46
neutrons
8
Other Items
• Know how to balance equations
• Be able to calculate weight % of an element
in a compound
• Be able to convert between mass and moles
and mass and number of molecules, number
of atoms
– 18 g of water has how many atoms?
