What to Focus On

  • p-block elements occur in both free and combined states.
  • Noble gases occur only in free state.
  • Oxygen, silicon, aluminum, and nitrogen are highly abundant.
  • Outer configuration: ns²np¹⁻⁶.
  • p-orbitals fill from left to right across a period.
  • Group 13: ns²np¹, Group 14: ns²np², ..., Group 18: ns²np⁶.
  • Atomic size decreases across a period (left to right).
  • Atomic size increases down a group.
  • Reason: Increasing nuclear charge vs. addition of shells.

Common Mistakes to Avoid

Atomic size increases across a period because more electrons mean a bigger atom.

Ionization enthalpy always increases smoothly across a period without exceptions.

Fluorine has the highest electron gain enthalpy (most negative) among halogens.
