  • The atoms that are bonded to it (correct)
  • Non-bonding electrons
  • The electronegativity of the central atom
  • The bond angles of the molecule

    • In a line-angle formula, what is assumed to be present wherever two lines meet or a line begins or ends?

  • Nitrogen atoms
  • Carbon atoms (correct)
  • Hydrogen atoms
  • Oxygen atoms
