Question

what is the basis of a metallic bond? the attraction of neutral metal atoms. the attraction between protons and neutrons. the attraction between positive metal ions and free floating electrons. the attraction between positive metal ions and interlocking electrons.

Explanation:

Metallic bonds form when metal atoms lose electrons, creating positive ions. These ions are surrounded by a sea of free - floating electrons. The electrostatic attraction between the positive metal ions and the free - floating electrons is what holds the metal together.

• Option 1: Neutral metal atoms do not form the basis of metallic bonds as metallic bonding involves ion - electron interactions.
• Option 2: Protons and neutrons are within the nucleus and their attraction is not related to metallic bonding.
• Option 3: Correct as per the description of metallic bonding.
• Option 4: There is no such thing as interlocking electrons in the context of metallic bonding; it is about free - floating electrons.

Answer:

1. the attraction between positive metal ions and free floating electrons.
