What terminology best describes the bonding in the following schematic of a metal?

Question

Quizplus · Accepted Answer

The electron-sea model is the most appropriate description for the bonding in a metal, in which the valence electrons of metal atoms create a "sea" of mobile electrons that can move freely throughout the metal lattice, interacting with all of the metal cations. This model explains many of the key properties of metals, including high electrical and thermal conductivity, malleability, and ductility. The other options (ionic bonding, covalent bonding, and crystal model) do not fully capture the nature of the bonding in a metal.
