Interactive video lesson plan for: Ionization Energy Electron Affinity Atomic Radius Ionic Radii Electronegativity Metallic Character

Activity overview:

This chemistry video tutorial explains the concepts of periodic trends such as first ionization energy, electron affinity, atomic radius, and ionic radii, electronegativity and metallic character. It contains plenty of examples and practice problems.

Here is a list of topics:
1. Periodic Trends - Atomic Size
2. Atomic Radii - Effective Nuclear Charging - Adding Protons to Increase The Charge of the Nucleus
3. Inner Core Electrons vs Outer Valence Electrons
4. Atomic Radius Increases from left to right
5. Atomic Radii Increases from top to bottom on the periodic table
6. Shielding Effect and Electron Repulsion
7. Coulomb's Law Equation / Formula - Relationship Between Electrostatic Force, Distance, and Charge - like charges repel and opposite charges attract.
8. Ionic Radii Trend - Cations vs Anions
9. Positively Charged Ions are Smaller Than Parent Neutral Atom
10. Negatively Charged Ions are Larger Than Parent Atom
11. How to calculate the number of electrons in an atom or ion
12. Principal quantum number and number of shells - atomic size
13. How to rank the elements in order of increasing atomic radii
14. how to rank isoelectronic ions in decreasing order of atomic / ionic size
15. isoelectronic species - same electron configuration
16. Metallic Character Trend - Metals vs Nonmetals
17. Electronegativity Trend - The ability of an atom to attract an electron to itself - increases toward fluorine
18. Electronegative Nonmetals vs Electropositive Metals
19. First Ionization Energy Trend - Increases left to right and bottom to top across a group
20. Ionization Energy - Energy required to remove an electron from a gaseous atom
21. First Ionization Energy vs Second Ionization Energy
22. Jump in Ionization Energy - Number of Valence Electrons
23. Ionization Energy Exceptions - Paired vs Unpaired Electrons in 2s and 2p orbitals
24. Electron Affinity Trend - The Energy change associated with the addition of an electron to a gaseous atom
25. Exothermic vs Endothermic Electron Affinity Processes
26. Half Filled vs Empty S and p orbitals
27.
