Stibine overview

The stored Lewis connectivity is SbH₃. Antimony forms three Sb–H bonds and keeps one lone pair, giving an AX₃E arrangement.

How to draw SbH₃

  1. Count 8 valence electrons. Include charge adjustments before drawing.
  2. Use the reviewed connectivity SbH₃. Do not infer a different isomer from the formula alone.
  3. Place the required single, double or multiple bonds. Keep a running electron total.
  4. Complete terminal valence shells and add lone pairs or formal charges. Antimony forms three Sb–H bonds and keeps one lone pair, giving an AX₃E arrangement.
  5. Verify the total electron count and geometry. The reviewed geometry is Trigonal pyramidal, about 91.3°.

Why this example matters

Antimony forms three Sb–H bonds and keeps one lone pair, giving an AX₃E arrangement.

Scope and model limits

The Lewis/VSEPR model is qualitative; heavier-atom bonding is not fully captured by a simple hybridization label.

Common mistakes

  • Omitting the antimony lone pair
  • Calling SbH₃ trigonal planar
  • Using multiple Sb–H bonds
