  1. Question 1

    Q1. Metals are excellent conductors of electricity in both solid and molten states. This property is explained by the:

    • A) Fixed positions of ions in the lattice
    • B) Presence of mobile, delocalized electrons
    • C) Strength of the electrostatic attractions
    • D) Directional nature of the metallic bonds

    Answer: Presence of mobile, delocalized electrons

    Explanation: The electron pool allows charge to flow freely through the lattice. Option A fails because ionic solids have fixed ions in crystals.
