Tell us about the structure of crystal lattices of metals. What kind of bond is called a metal bond? Why do different metals have some of the same properties?

In the nodes of the metal crystal lattice there are positively charged ions and neutral atoms, between which electrons move.
The bond that is made by relatively free electrons between the metal ions that form the crystal lattice is called a metal bond.
The general structure of the crystal lattices of metals determines their general properties: high thermal and electrical conductivity, ductility, plasticity, metallic luster.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
