A scientist is investigating the chemical properties of a hydrogen atom (H), which has an electroegativtiy of 2.1, and a chlorine atom (Cl), which has an electronegativity of 3.0. Suppose these two atoms form a chemical bond resulting in the compound HCl. Predict whether the compound is held together by an ionic, a polar covalent, a nonpolar covalent, or a hydrogen bond. Explain your prediction. Describe the bond in terms of its electrical charg
