How do crystal lattices of metals differ in structure and properties from ionic and atomic crystal lattices?

The crystal lattice is called a specific arrangement of particles of a substance.
At the sites of the ionic lattice are ions that make up the molecule, such a lattice in substances with an ionic type of bond – basic oxides, salts; they are hard and refractory.
Atoms lie in the nodes of the atomic lattice; this is a strong bond. and the substances are very hard (eg: diamond, silicon oxide).
At the nodes of the metal lattice, atoms and ions of metals alternately lie, and the space between them is free electrons, hence the electrical conductivity of metals.
