Physical Science Test 4 Study Guide What to study: • This study guide • The notes on the website and that I handed out in class. • Review your past quizzes, labs and class activities (atom building simulator, electron shell questions) • The following pages from the book: ◦ 453-457 atoms/history of the atomic structure ◦ 570-577 model of the atom ◦ 500-530 periodic table and organizing elements Know how to... • Describe some of the historical development of atomic theory. ◦ Example: What was John Dalton’s contribution to atomic theory? How has atomic theory changed since Daltons time? ◦ Example: What is one experiment or observation which supports atomic theory. •
Utilize the definition of the following terms: ◦ nucleus valence electron electronegativity reactivity group period isotope shell proton neutron electron mass atomic number neutral net charge ■ ■ ■
reactive/ electron atomic
Example: What does it mean if an atom has a neutral net charge? Example: Which particles are in the nucleus of an atom? Example: There are two isotopes of Lithium. What is different about these two isotopes in terms of the particles? What is different about these two atoms in terms of the mass, charge, or atomic number?
•
Utilize the differences between the subatomic particles ◦ Example: How are protons different from electrons? ◦ Example: What is the net charge of two protons and one neutron?
•
Draw a picture of an atom given a description of the atom ◦ Example: Draw the following atom: Lithium, Charge of +1, Atomic Mass of 5
•
Describe how the various particles affect the properties of an atom ◦ Example: Which particles affect the mass of an atom? Why don’t all of the particles affect the mass?
Name:
Physical Science Date:
Mr. Nestlerode Period: • Describe the Structure of the Periodic table using the concept of electrons orbitals ◦ Example: The first row of the periodic table has 2 elements. The second row has 8 elements. Why? •
Determine the number of valence electrons that an atom has ◦ Example: How many valence electrons do the following atoms have: Sodium Oxygen Hydrogen Argon
•
Determine the electronegativity of an element. ◦
Example: Rank the following in terms of electronegativity (lowest to highest) Sodium Sulfur Chlorine Silicon
•
Determine whether an atom wants to gain or lose and electron using the filled shelled rule ◦ Example: For each element, state how many electrons it wants to gain or lose. Write “stay the same” if the atom does not want to gain or lose. Sodium Sulfur Chlorine Silicon
•
Identify the following periodic table families and some of their properties: Noble Gas Halogen Alkali Metal Alkaline Earth Metal Non-Metal Transition Metals ■ ■ ■
•
Example: Where are the Alkali Metals on the periodic table? Describe how reactive the elements in this family are. Example: Name two transition metals. Example: Which family is Argon in?
Use the filled shell rule to predict what will happen when two elements are mixed ◦ Example: Which of the pairs listed below would likely react when they are mixed: ■ Argon and Sodium ■ Oxygen and Magnesium ■ Magnesium and Lithium ■ Sodium and Chlorine
