Questions & Step-by-Step Solutions

What is the electron pair geometry of NH3?
  • Step 1: Identify the molecule you are analyzing, which is NH3 (ammonia).
  • Step 2: Count the number of atoms bonded to the central atom (nitrogen). In NH3, nitrogen is bonded to three hydrogen atoms.
  • Step 3: Determine the number of lone pairs on the central atom (nitrogen). Nitrogen has one lone pair of electrons.
  • Step 4: Add the number of bonding pairs (3 from hydrogen) and lone pairs (1 from nitrogen) together. This gives you a total of 4 electron pairs.
  • Step 5: Use the total number of electron pairs to determine the electron pair geometry. With 4 electron pairs, the geometry is tetrahedral.
