To find this value you set up the chart shown below. Remember to go left to right. Then total up the bonding and antibonding electrons and calculate the bond order. The greater the bond order, the greater the bond strength. Also, while bond order increases, bond energy increases and bond length decreases.
Paramagnetism is when a substance is attracted into an inducing magnetic field.
Diamagnetism is when the substance is repelled by an inducing magnetic field. Looking at the stack chart can identify paramagnetism.
