The structure of a metal can be described as follows:

1. Atomic Structure: Metals are made up of atoms which are densely packed together. These atoms are arranged in a regular pattern, often in a 'crystal lattice' structure. This regular, repeating pattern extends in all three spatial dimensions.

2. Metallic Bonding: The atoms in metals are held together by metallic bonds. This type of bond occurs when the valence electrons are free to move throughout the structure, creating a 'sea' of delocalized electrons. This sea of electrons is what gives metals their unique properties such as conductivity and malleability.

3. Layers of Atoms: In most metals, the atoms are arranged in layers. This layered structure allows the layers to slide over each other when a force is applied, making metals malleable and ductile.

4. Positive Ion Centers: In the metallic bond, the metal atoms lose their valence electrons to the 'sea' of electrons. This results in each metal atom becoming a positive ion. These positive ions are then attracted to the negatively charged electron sea, holding the structure together.

5. Dense Packing: The atoms in a metal are packed together tightly. This dense packing contributes to the high density and strength of metals.
