The Periodic Table: Atomic Radius, Ionization Energy, and Electronegativity
Guided Notes
3 key concepts
- 1
As you move down the periodic table, the atomic radius increases because you are adding more electron shells.
- 2
Ionization energy is the energy required to remove an electron from an atom, and it generally increases as you move up and to the right on the periodic table.
- 3
Electronegativity, or the ability of an atom to hold electrons tightly, generally increases as you move up and to the right on the periodic table.
