📊 The Periodic Table — Key Features

Annotated periodic table showing groups (vertical columns) and periods (horizontal rows). Group 1 alkali metals are highlighted in purple, Group 7 halogens in red, Group 0 noble gases in green, and transition metals in grey. Includes key information about metals vs non-metals and important trends.

KEY: Elements are arranged by atomic number (not mass!). The table reveals patterns — elements in the same group have similar chemical properties.
