Increases across a period; decreases down a group.

The bridge. Carbon is the basis of life; Silicon is the basis of technology.

Decreases across a period (increasing nuclear charge pulls electrons closer) and increases down a group. MAIN GROUP CHEMISTRY, (Tutorial Chemistry Texts)

Famous for electron deficiency. Boron forms unique "cluster" compounds (boranes) that challenge standard bonding rules.

Elements like Lithium and Magnesium share similar properties because their charge-to-size ratios are almost identical. Increases across a period; decreases down a group

This is where chemistry gets diverse, moving from metals to metalloids to non-metals.

Main Group Chemistry: A Primer Main group chemistry focuses on the (Groups 1 and 2) and p-block (Groups 13–18) elements . Unlike transition metals, these elements primarily involve the filling of Decreases across a period (increasing nuclear charge pulls

+2 oxidation state. Harder and less reactive than Group 1, but still form basic oxides. Magnesium and Calcium are biologically essential. 3. The p-Block (Groups 13–18)
