How would you Describe the structures of metals in terms of particles present in their structures?

Metals are characterized by a crystalline structure composed of closely packed atoms, typically arranged in a regular pattern known as a lattice. The atoms in metals are held together by metallic bonds, which involve a "sea of delocalized electrons" that are free to move throughout the structure, allowing for conductivity and malleability. This arrangement of positively charged metal ions surrounded by a sea of electrons gives metals their unique properties, such as strength and ductility. Overall, the particle structure of metals contributes significantly to their physical characteristics.
