What is a crystal lattice, what is an ionic crystal lattice. Give examples of substances with an ionic crystal lattice.

The crystal lattice is the spatial arrangement of particles in a substance (molecules, atoms, ions).
Lattices are atomic, molecular, metallic and ionic. The ionic crystal lattice at its sites has an alternating arrangement of positively and negatively charged ions. Such a lattice is found in substances with an ionic type of bond, that is, in basic oxides, salts and bases. For example: calcium oxide, sodium chloride, copper hydroxide. Substances with an ionic lattice are always solid, refractory.



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
