Final answer:
The bonding model for sodium metal is different from the bonding model for sodium chloride. Sodium metal consists of positively charged sodium ions attracted to each other in a metallic lattice, while sodium chloride is held together by ionic bonds, forming a crystal lattice structure.
Step-by-step explanation:
The bonding model for sodium metal differs from the bonding model for sodium chloride, NaCl. Sodium metal is composed of individual sodium atoms that lose their outermost valence electron to become positively charged sodium ions. These ions are attracted to each other due to the strong electrostatic forces of attraction and form a regular arrangement called a metallic lattice. On the other hand, sodium chloride is formed by the transfer of an electron from sodium to chlorine, resulting in the formation of Na+ and Cl- ions. The positive and negative ions are held together by ionic bonds, forming a crystal lattice structure.
