The General Periodic Trends
Understand the gerenal trends demonstrated by the five periodic properties requies us to put together our understanding of the trends definitions and the changes in atomic structure across and down the table.
The trends themselves are simple to state:
Ionization Energy increases up and to the right
Electron Affinity increases up and to the right
Electronegativity increases up and to the right
Atomic Radius increases down and to the left
Ionic Radius increases down. Going across, it intially decreases, then increases dramatically, then decreaes again.
