Chapter 4 Study Guide

Answer the following questions on a separate sheet of paper.

  1. Define the terms: protons, neutrons, electrons, nucleus, energy level/electron ring.
  2. What does the atomic number tell you about the element? What does the mass number tell you about the element?
  3. If you know how many protons are in an element, you can figure out the number of neutron? Electrons?.
  4. What is an isotope? What is the atomic mass of an element?
  5. Who is Dmitri Mendeleev? What did he do?
  6. How is the modern periodic table arranged? What can you predict based on an elements location on the periodic table?
  7. Which metals group on the periodic table is the most reactive? Which nonmetals group is least reactive? Explain why.
  8. What are the group numbers of the transition metals?
  9. What elements are included in the Halogen family. What is the group number?
  10. Compare the terms group and period. In which do the elements have similar properties? In which do the elements have the same number of valence electrons? Which has the same number of electron rings?
  11. What is another name for group?
  12. If you have the atomic number and the mass number, how did you figure out how many protons, neutrons and electrons the element has?
  13. What does the zig-zag line on the periodic table represent? Which elements are found along the zig-zag line?
  14. What does reactivity mean? What determines an element’s reactivity?
  15. What are the main physical properties of metals?
  16. What are the main physical properties of nonmetals?
  17. Compare the terms malleable, ductile and brittle.
  18. What are the Noble gases? Are they reactive or unreactive? Why?
  19. What are semimetals? What properties do they have?
  20. Know how to draw a Bohr model (see atomic radii activity) of any elements in periods 1,2 and 3.
  21. What are valence electrons and why are they significant? (include the word chemical bond in your explanation)
  22. As you move down a column in the periodic table, does the atomic mass increase or decrease? Does the atomic number increase or decrease? Does the reactivity increase or decrease?
  23. Be able to predict what elements will bond with each other. Match the element on the left to the element(s) on the right that it would bond with to make a compound by using a periodic table.

Sodium (Be) Bromine (Br)

Potassium (K )Lithium (Li)

Chlorine (Cl) Three Hydrogen (H)

Nitrogen (N)Oxygen (O)

Carbon (C)Four Hydrogen (H)

TIPS!!!

Re-read your Atomic Parts worksheet and Atmoic Radii Activity

Look over your notes (PowerPoints), labs, and activities for the unit.

Look at the Chapter’s section assessments. Look over assigned homework and warm ups.

Use your notes and textbook to clarify anything.

Use or for review activities
