- Electrons in Atoms
- Periodic Properties
- Ionization Energies
- energy required to remove the valance electron from an ion or gaseous atom
- Atomic Radius
- half the distance between the centers of two atoms that are touching each other
- Electronegativity
- measure of the ability of an atom to form a chemical bond
- Electron Affinity
- ability of an atom to accept an electron
- Trends of Periodicty
- Moving left - right
- Ionization energy increases
- Electronegativity Increases
- Atomic radius decreases
- Electronegativity Increases
- Ionization energy increases
- Moving left - right
- The periodicity of these properties follows trends as you move across a row or period of the periodic table or down a column or group
- Ionization Energies
- Electron Configuration
- e.g Electron Configuration for Sodium (atomic number 11) = 1s2, 2s2, 2p6, 3p1
- Periodic Properties
