Lesson 6.1 Guided Notes
Answer questions 1 & 2 after watching the “Octet Rule Song” video:
https://www.youtube.com/watch?v=WzWk-mx_14E
1. State the Octet Rule in your words.
2. Why is the Octet Rule important?
Answer questions 3 & 4 after watching the “Atoms Form Ions” video:
https://www.youtube.com/watch?v=x4IoMrlths0
3. How can an atom with 7 valence electrons become more stable?
4. How can an atom with 2 valence electrons become more stable?
5. On the periodic table number the groups by their valence electrons (Slide 10).
8. Would it be easier for halogen atoms to gain 1 more electron, or give away 7 electrons to have a full outer
energy level?
Answer questions 9 & 10 after watching the video ‘Ion Charges Explained”.
https://www.youtube.com/watch?v=vQO7oZwB5iw
9. Label the ion charges for the groups on the periodic table below each group.
10. Label the transition metals on the periodic table. Can the ion charges for these elements be determined by
looking at their position on the table?
Notes:
Slide 15:
• The ions with positive (+) charges are metals
• The ions with negative charges (-) are nonmetals
Slide 16: Metals
• Usually have 1-3 valence electrons, which they give away
• Lose electrons, leaving them with more protons than electrons, causing an overall positive charge
• Form cations (positive ions)
Slide 17: Nonmetals:
• Usually have 5-7 valence electrons, which they keep
• Gain electrons, leaving them with more electrons than protons, causing an overall negative charge
• Form anions (negative ions)
11. Complete the chart on your own and then check answers with a partner:

12. Why doesn’t the last group (noble gases) have an ion charge?
