The bond between sodium and chlorine in NaCl is
Answer and explanation
Correct answer: B. ionic
- Step 1: Chemical bonding is classified primarily based on the electronegativity difference between the constituent elements.
- Step 2: Sodium () is an electropositive metal that readily loses its valence electron, while chlorine () is a highly electronegative non-metal that readily accepts an electron.
- Step 3: The complete transfer of an electron yields and ions held together by strong electrostatic attraction, forming an ionic bond.
Answer
ionic.
Why not the others: Covalent bonding involves shared electron pairs between nonmetals; metallic bonding involves delocalized electrons in a lattice; hydrogen bonding is an intermolecular force involving H bonded to N, O, or F.
