1) This statement is true because the stability of a molecule is directly related to the number of bonding and antibonding electrons. If the number of bonding electrons is greater than the number of antibonding electrons, the molecule is predicted to be stable.
2) This statement is partially true. Bond order is the difference between the number of bonding electrons and the number of antibonding electrons, but it is not divided by 4. Bond order is simply the difference between these two types of electrons.
3) This statement is also true. If the bond order of a molecule is high, its bond strength is also high. This is because the number of bonding electrons in the molecule is directly related to the strength of the bond between the atoms involved.
