Questions & Step-by-Step Solutions

What is the bond angle in the water molecule (H2O)? (2023)
  • Step 1: Understand that a water molecule (H2O) consists of one oxygen atom and two hydrogen atoms.
  • Step 2: Recognize that the oxygen atom has two lone pairs of electrons that are not involved in bonding.
  • Step 3: Know that these lone pairs push the hydrogen atoms closer together, creating a bent shape.
  • Step 4: Measure the angle between the two hydrogen atoms; this is called the bond angle.
  • Step 5: Conclude that the bond angle in a water molecule is approximately 104.5 degrees.
