1 Name: Period: Date: UNIT 3: Electrons Lesson 4: The Octet Rule Do Now: By the end of today, you will have an answer to: What role do valence electrons play in chemical changes? Draw the following lewis dot diagrams. Nitrogen Neon Carbon He List two elements that have similar chemical properties to Fluorine. Explain your answer. THINK ABOUT IT!!! Potassium atom Potassium is the eighth most abundant element on the earth, but it is never found free in nature. Draw the lewis dot diagram for potassium (K). Number of protons: Number of neutrons: Number of electrons: Electron Configuration: Potassium Ion Potassium ions are necessary for the function of all living cells. Here is the Lewis dot diagram for potassium ion (K + ). Number of protons: 19 Number of neutrons: 20 Number of electrons: 18 [K] + Electron Configuration: COMPARE AND CONTRAST: How are potassium atoms different from potassium ions? THINK ABOUT IT: A potassium ion (K 1+ ) has a +1 charge. Explain, in terms of subatomic particles why it has a charge of +1.
2 The Octet Rule: Every element wants eight valence electronsa full valence electron shell. Noble Gases (Group 18) are the most stable atoms. Why is this statement true based on the octet rule? Formation of Ions: What happens to an atom that does not have a full octet? IONIZATION ENERGY (definition): Example: 1. From which of these atoms in the ground state can a valence electron be removed using the least amount of energy? (1) Nitrogen (2) Carbon (3) Oxygen (4) Chlorine GIVE IT A TRY! Determine the number of electrons needed to fulfill the octet rule. Circle whether it is easier to gain or lose electrons. Na O N Si Ne F THINK and WRITE: Why does it make sense that sodium has a lower ionization energy than carbon?
3 Net Charge: How does an atom of an element differ from an ion of that same element? Vocabulary Definition Examples Ion Anion Cation In terms of the number of subatomic particles, what does it mean if an ion has a positive charge? A negative charge? ATOM CATION (POSITIVE CHARGE) ANION (NEGATIVE CHARGE) Example: What ion will the following atom form? 1. How many protons does this atom have? 2. How many electrons does this atom have? 3. How many electrons does this atom need gain or lose in order to fulfill a full octet? Gain: Lose: 4. What is the electron configuration of the Li ion? 5. What is the charge of this ion? 6. Which noble gas configuration does the Li ion have? SUMMARIZING QUESTIONS: 1. How is an ion different from an atom? 2. What is the charge of a calcium ion? 3. What does it mean if an ion has a negative charge?

(1) 24 (2) 26 (3) 28 (4) Which electron configuration is correct for a sodium ion? (1) 2 7 (2) 2 8 (3) (4) Compared to a calcium atom, the calcium ion Bromine atom: ion: Charge of protons: Charge of electrons: Charge of the ion: Ca 2+ has (1) more protons (2) fewer protons (3) more electrons (4) fewer electrons Sulfur atom: ion: Charge of protons: Charge of electrons: Charge of the ion: 7. Which atom in the ground state requires the least amount of energy to remove its valence electron? (1) Lithium atom (2) Potassium atom (3) Rubidium atom (4) Sodium atom 8. Which particle has the same electron configuration as a potassium ion? (1) Fluoride ion (2) Sodium ion (3) Neon atom (4) Argon atom 9. An atom of argon rarely bonds to an atom of another element because an argon atom has (1) 8 valence electrons (2) 2 electrons in the first shell (3) 3 electron shells (4) 22 neutrons 10. Which ion has the same electron configuration as an atom of He? (1) H - (2) O 2- (3) Na + (4) Ca +

When metals form ions, they tend to do so by (1) losing electrons and forming positive ions (2) losing electrons and forming negative ions (3) gaining electrons and forming positive ions (4) gaining electrons and forming negative ions Free Response Practice 13. Explain, in terms of electron configuration, why an oxygen ion is more stable than an oxygen atom. Use the information below to answer questions 14 and 15.
