What is the most correct relationship (like a trend) between bond length, bond energy, and bond order (for example between two carbon atoms) (Choose only one) (1.5 pts): a. Bond order increases then bond length increases then bond energy increases b. Bond order increases then bond length decreases then bond energy increases c. Bond order decreases then bond length increases then bond energy increases d. I would expect no relationship between these quantities 4. (2 pts) Electronegativity is a measure of The energy needed to remove an electron from an atom. The energy released when an electron is added to an atom. The magnitude of the negative charge on an electron. The attraction by an atom for electrons in a chemical bond. The magnitude of the negative charge on a molecule. 5. Which of the following elements is the most electronegative? (2 pts) a) S b) Ruc) Si d) Te e) Cs - During a chemical reaction, which statement is true? (Choose one; 2 pts) a) The breaking of chemical bonds requires energy input b) The formation and breaking of chemical bonds releases energy c) The breaking of chemical bonds releases energy d) The formation of chemical bonds requires energy input e) The formation of chemical bonds releases energy f) Both (a) and (e) are true
