Building Atoms HW
Read and outline (Cornell style) Section 4.1 AND 4.2 in your chemistry textbook. Then answer
the following assessment questions:
1. Define an atom using your own words.
2. Describe the structure of a typical atom. Be sure to identify where each subatomic
particle is located.
3. Make a table comparing the relative charge and mass of each of the subatomic particles.
4. For each of the following elements, give the name, atomic number, # of protons, # of
electrons, group number, and family/group name (if applicable):
a. S
b. Mg
c. N
d. Na
e. Se
f. Sr
