P-Block Elements Cheatsheet

Key Concepts & Characteristics

  • Definition: P-block elements are from groups 13 to 18 in the periodic table.
  • Valence Electrons: These elements have their valence electrons in p orbitals.
  • Groups: Includes Boron family, Carbon family, Nitrogen family, Oxygen family, Halogens, Noble gases.
  • General Properties: Diverse properties ranging from metals to nonmetals and inert gases.
  • Oxidation States: Variable oxidation states, often showing +3, +5, -3, etc.
  • Important Compounds: Oxides, halides, hydrides with unique acidic/basic properties.
  • Reactivity: Reactivity decreases down the group for Halogens, increases for Noble gases.
  • Electron Configuration: Outer electronic configuration is ns2 np1-6.
  • Uses: Wide applications in industry, medicine, and materials science.
  • Trends: Atomic size, electronegativity, ionization energy vary predictably across the block.

Quick Reference Table
