Describe the structure of metallic bonding in terms of positive ions and electrons.
Understand the Problem
The question is asking for a description of metallic bonding. This involves explaining how metal atoms arrange themselves and interact through their electrons to form a strong, cohesive structure. We need to highlight the roles of positive ions (cations) and delocalized electrons in this bonding model.
Answer
Metallic bonding consists of positive metal ions in a lattice, surrounded by a 'sea' of delocalized electrons, creating a strong attraction.
Metallic bonding involves a lattice of positive metal ions surrounded by a 'sea' of delocalized electrons. These electrons are free to move throughout the structure, creating a strong electrostatic attraction between the positive ions and the negative electron cloud, which holds the metal together.

Metallic bonding involves a lattice of positive metal ions surrounded by a 'sea' of delocalized electrons. These electrons are free to move throughout the structure, creating a strong electrostatic attraction between the positive ions and the negative electron cloud, which holds the metal together.
More Information
Metallic bonds are responsible for many of the properties of metals, such as their strength, ductility, malleability, and electrical conductivity.
Tips
A common mistake is to think the electrons are bound to individual atoms. They are delocalized and free to move throughout the metal structure.
