Ch 4 test preparation: Review all of your notes, worksheets, and homework questions. Read
sections 4.1, 4.2, 4.4, 4.6 through 4.11 in the book!
You must able to:
1. Find and read information off the periodic table: symbol, element name, atomic number, average
atomic mass.
2. Write the formula for a compound given the numbers of atoms. What does the subscript indicate?
3. Identify the basic parts of an atom, their charges, relative masses, and where found in the atom.
4. Discuss the relative width of the nucleus of a typical atom versus its overall diameter. What does this
imply about atoms?
5. Define isotope, atomic number and mass number.
6. Write an isotope symbol. Which part is the atomic number (# of protons)? Which part is the mass
number (# protons and neutrons)?
7. Compute the average atomic mass for an element computed,
8. Identify the 9 major areas of periodic table and select elements in each area. What is a group?
What is a period? Identify elements on the periodic table by their periods or groups. What do
elements in groups have in common? Why?
9. Describe the natural states of the elements, i.e., which are solids, liquids, or gases at around 25oC.
What is a diatomic molecule? Which elements are diatomic molecules in their pure form? (HONClBrIF
or BrINClHOF)
10. Explain why so few elements on the periodic table are found in pure form.
11. Define ion, cation and anion. How are ions formed? Use the PT to determine the charges on metal
and non-metal ions. How is the ionic charge on a transition metal determined?
12. Combine ions in correct ratios to form stable compounds without a charge.
