p-block

• 1. Block Elements

  13th - 18th group in the periodic table, most elements are non-metal, but also includes metal & metalloids, the p-subshell includes 3 orbitals, with a total of 6 orbitals

  
• Electron Configuration

  General electron configuration: ns2np(1-6), Elements in p-block have their valence electrons in the p orbital, The number of electrons in the p orbital increases as the column number increases
• Electron Configuration Examples

  • Carbon (group 14): 1s22s22p2
  • Nitrogen (group 15): 1s22s22p3
• Properties of P-Block Elements

  • P-block elements include metalloids, nonmetals, and metals
  • Their electron configuration involves occupying p-orbitals
  • Many p-block elements can have multiple oxidation states
  • Nonmetals in the p-block tend to have higher electronegativity
  • Reactivity and bonding behavior vary among p-block elements
  • Some p-block elements exhibit allotropy
  • All the elements in this group are polyatomic
  • Metallic characteristics increase down the group
  • Boiling points increase top to bottom
  • Melting point increases upto arsenic and decreases upto bismuth
  • Except "N" all elements exhibit allotropy
