Science Review Sheet: Periodic Table Test
Name:_______________________
Study periodic table notes. Know the properties of Alkali Metals, Alkaline Earth Metals,
Halides/Halogens and Noble Gases. Know how to calculate atomic mass, # of protons, # of
electrons, and #of neutrons in an atom.
1. What are the three subatomic particles? Where are they found within an atom? What charge do
they have? How do the masses of the three subatomic particles compare?
2. What is the difference between the atomic number and atomic mass of an element in the periodic
table?
3. What are the "energy levels" of an atom? How do we find them on the periodic table?
4. What do valence electrons tell us about an atom?
5. Draw a Bohr diagram of the element with an atomic # of 13. How many energy levels and valence
electrons does this element have? What is this element?
6. What are the rows of elements on the periodic table called? What do the elements in the different
rows have in common with each other?
7. What are the columns on the periodic table called? What do the elements in each column of the
periodic table have in common with each other?
8. What makes an atom stable?
9. How does reactivity change as you go from the top of a group to the bottom of the group?
List the different properties of Metals, Nonmetals, and Metalloids. Know how to find them on
the periodic table. Also know that metals are to the left of the zigzag line, metalloids touch the
zigzag line on both sides (exception Al), and that nonmetals are to the right of the zigzag line.
Metals
Nonmetals
Metalloids
9. List at least 4 physical properties.
10. List at least 4 chemical properties.
11. What element is indicated by the Bohr model shown below?
12. What are the elements in group 8a called? What makes them unique compared to other
elements?
13. Name an element that is found in group 7 and period 3.
14. What are the rules for the number of electrons allowed in each of the first 3 energy levels?
