Chemistry 04：Periodic Table 02

In this Originals content activity, students will continue to look at some other trends that exist in the periodic table.

Activities:

I.   Ionization Energy:

• 💡 Originals Content Tip: Use the “polls” feature and ask students how they think ionization energy would change across and down the periodic table.
• Explain how ionization energy changes on the periodic table by drawing out an example of a small and large atom.
• Conclusion: Teachers/students may write down the conclusion of how ionization energy changes across and down the periodic table.

II.  Electron Affinity:

• 💡 Originals Content Tip: Use the “polls” feature and ask students how they think electron affinity would change across and down the periodic table.
• Explain how electron affinity changes on the periodic table by drawing out an example of a small and large atom.
• Conclusion: Teachers/students may write down the conclusion of how electron affinity changes across and down the periodic table.

III. Electronegativity:

• 💡 Originals Content Tip: Use the “polls” feature and ask students how they think electronegativity would change across and down the periodic table.
• Explain the octet rule and how electronegativity changes on the periodic table by drawing out Fluorine and Lithium.
• Conclusion: Teachers/students may write down the conclusion of how electronegativity changes across and down the periodic table.

IV. Periodic Trends

• Use arrows to draw how atomic radius, ionic radius, electron affinity, ionization energy, and electronegativity change across and down the periodic table in an increasing direction.
