Which statement about metallic bonding is correct?
Answer and explanation
Correct answer: B. Positive ions are held together by a sea of delocalised electrons
- Step 1: Delocalised electrons also explain why metals conduct electricity. Answer: Positive ions are held together by a sea of delocalised electrons. Why not the others: Atoms share pairs of electrons: That is covalent bonding. Electrons are transferred from metal to non-metal: That is ionic bonding. Molecules are held by weak forces: That describes simple molecular substances.
