Which of the following statements is true of chemical bonds? A) Both ionic and covalent bonds involve electrons in the innermost shell. B) Covalent bonds share electrons between two atoms. C) An atom involved in an ionic bond has an equal number of electrons and protons. D) Salts are covalently bonded. E) The atoms in a molecule of water (H₂O) are bonded together with ionic bonds.

Question

Quizplus · Accepted Answer

Covalent bonds involve the sharing of electrons between two atoms. Ionic bonds involve the transfer of electrons from one atom to another. A) is incorrect because only ionic bonds involve the transfer of electrons between atoms, and not necessarily in the innermost shell. C) is incorrect because an atom involved in an ionic bond will have a different number of electrons and protons due to the transfer of electrons. D) is incorrect because salts are typically held together by ionic bonds. E) is incorrect because water molecules are held together by polar covalent bonds, not ionic bonds.
