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.

Use the figure to find the electronegativity difference between each of the following pairs of elements, then use the table below to classify the bonds that occur between them as pure covalent, polar covalent, or ionic. (Electronegativity of CrCr is 1.6)   Electronegativity Difference (ΔENΔEN) Bond Type Example zero (0−0.40−0.4) pure covalent Cl2Cl2 intermediate (0.4−2.00.4−2.0) polar covalent HFHF large (2.0+2.0+) ionic NaClNaCl     Find the electronegativity difference between Br and Br. Express your answer using two significant figures.
