The statement that best describes the types of bonds shown in the diagram is:
a covalent bond; the hydrogen atom’s single electron is being shared with the chlorine atom.
In a hydrogen chloride (HCl) molecule, hydrogen (H) has one electron and chlorine (Cl) has seven valence electrons. They form a covalent bond by sharing the single electron from hydrogen with one of the electrons from chlorine, which allows both atoms to achieve a more stable electron configuration.
