Chemistry of Periodic Trends
The periodic table is organized so that elements with similar properties fall into columns (groups). This organization reveals predictable **Periodic Trends**:
ElectronegativityGenerally increases from left to right and bottom to top. Fluorine is the most electronegative element.
Atomic MassTypically increases as you move down a group and right across a period as more protons and neutrons are added.
