What to Focus On

  • Transition elements belong to groups 3 to 12.
  • The differentiating electron enters the (n-1)d subshell in transition elements.
  • Inner transition elements have differentiating electrons in the (n-2)f subshell.

  • Transition elements commonly have (n-1)d1-10 ns1-2 configurations.
  • Chromium has [Ar]3d5 4s1 due to extra stability of half-filled subshells.
  • Copper has [Ar]3d10 4s1 due to extra stability of completely filled subshells.

  • Atomic radii decrease across a transition series and become nearly constant after midway.
  • Atomic radii increase slightly near the end of a series.
  • Atomic radii increase down a group.

Common Mistakes to Avoid

All d-block elements are true transition elements.

Copper is not a transition element because its atom has a filled d-subshell.

Cr and Cu follow the normal aufbau order exactly.
