Answer 1

1) Electronegativity difference in H-H bond is zero Hydrogen electronegativity is 2.1 -H H 2.1 2.1 2) Which bonds are considered ionic? Select all that apply. & Al-F Cl-Na AI-AI OH-F K-1 CI-CI Metal and non metal are react to form ionic. Aluminium is metal and fluorine is nonmetal . Metal and non metal are react to form ionic. AL-F bond is ionic Na - Cl bond is ionic H-F bond is polar covalent. HF is a polar covalent compound, fluorine is most electronegative among all the halogens when it reacts with hydrogen it forms a covalent compound Potassium iodide (KI) forms an ionic bond.
