- Question 6 Which statement below is true? Hint: Consider how properties of a covalent bond are measured. O One mole of hydrogen atoms is more stable than one mole of hydrogen molecules, O As the distance between the nuclei decreases when forming a covalent bond, there is a corresponding decrease in the probability of finding both electrons near either nucleus O The bond energy is the minimum energy required to bring about pairing of the electrons in a covalent bond. O The buildup of electron density between two atoms repels each nuclei, making them less stable O The two electrons in a single covalent bond must be paired as required by the Pauli exclusion principle.
