You're on a roll — here are the answers for Part 1: Multiple Choice. 1. Which of the following best describes metallic bonding? c) The electrostatic attraction between positive metal ions and delocalized electrons. This option accurately describes metallic bonding as the attraction between the positively charged metal ions and the surrounding mobile "sea" of delocalized electrons. 2. In the "sea of electrons" model, what are the electrons referred to as? c) Delocalized. Delocalized electrons are not bound to any single atom but are free to move throughout the entire metallic structure. 3. Which property of metals is not directly explained by the "sea of electrons" model? c) Brittleness. Metals are generally not brittle; they are malleable and ductile. Brittleness is a characteristic of ionic compounds, where a shift in layers causes repulsion and fracture. The "sea of electrons" model explains properties like conductivity, malleability, and thermal conductivity. 4. Why are metals good conductors of electricity? b) Their delocalized electrons can move freely and carry charge. The mobile, delocalized electrons in the metallic lattice can easily move in response to an electric field, allowing for efficient charge transfer. 5. What happens to the metal atoms when a metal is hammered into a new shape (malleability)? b) The layers of positive ions slide past each other without disrupting the metallic bond. The "sea of electrons" allows the layers of positive metal ions to slide over one another without breaking the overall metallic bond, which explains why metals are malleable and ductile.
