Topics in The p-Block Elements
1
General Characteristics of p-Block Elements
- Electronic configuration: ns²np¹⁻⁶ (except He which is 1s²)
- Six groups: 13 (Boron family), 14 (Carbon family), 15 (Nitrogen family), 16 (Oxygen family), 17 (Halogens), 18 (Noble gases)
- Atomic radii decrease across period, increase down group
2
Group 13 Elements (Boron Family)
- Elements: B, Al, Ga, In, Tl with electronic configuration ns²np¹
- Boron is non-metal, rest are metals due to small size and high IE of boron
- Common oxidation state: +3, but Ga, In, Tl also show +1 due to inert pair effect
3
Group 14 Elements (Carbon Family)
- Elements: C, Si, Ge, Sn, Pb with electronic configuration ns²np²
- C and Si are non-metals, Ge is metalloid, Sn and Pb are metals
- Oxidation states: +4 and +2 (due to inert pair effect in heavier elements)
4
Important Compounds and Their Reactions
- Boric acid (H₃BO₃): Weak monobasic Lewis acid, accepts OH⁻ ions
- Borax (Na₂B₄O₇·10H₂O): Used as flux, antiseptic, and in glass making
- Aluminum oxide (Al₂O₃): Amphoteric, used in extraction of aluminum
