Final answer:
The compound that results from the formation of an ionic bond among the options given is C) NaCl (sodium chloride), which is formed by the transfer of electrons from the metal sodium to the nonmetal chlorine.
Step-by-step explanation:
The student has asked which of the following compounds results from the formation of an ionic bond:
- A) H₂O (water)
- B) CO₂ (carbon dioxide)
- C) NaCl (sodium chloride)
- D) CH₄ (methane)
Ionic bonds are formed when metal atoms lose one or more of their electrons to nonmetal atoms, creating a compound consisting of cations and anions held together by electrostatic attraction. In the list provided, NaCl (sodium chloride) is an ionic compound. It forms when electrons from sodium atoms are transferred to chlorine atoms, resulting in positively charged sodium ions (Na+) and negatively charged chloride ions (Cl−), which then attract each other to form the solid ionic structure known as table salt.
Options A (H₂O, water) and B (CO₂, carbon dioxide) result from covalent bonds, where atoms share electrons rather than transferring them. Option D (CH₄, methane) also involves covalent bonding between carbon and hydrogen atoms. Therefore, the correct answer is C) NaCl (sodium chloride).
