Guided Notes
3 key concepts
- 1
According to Coulomb's Law, the magnitude of force between two charged particles is proportional to the product of their charges divided by the distance between them squared.
- 2
The effective nuclear charge (Zeff) is the charge felt by valence electrons, and it can be approximated by the atomic number minus the number of core electrons.
- 3
Ionization energy generally increases as you move up and to the right on the periodic table, while atomic radius generally decreases in the same direction.
