Презентация на тему Types of chemical bonds in crystals

crystal formation. Crystals are defined as a solid state

of matter in which atoms are packed together tightly. The distinguishing feature of crystals is that their solid form is symmetrical on all sides. The specific geometrical shape of crystals is called a crystal lattice. When the electrons of atoms combine with surrounding atoms, a chemical bond is consummated, and crystals are formed.

their orbits to bond with the corresponding supporting atom.

The resultant combination of negatively or positively charged electrostatic forces stabilizes ions. The physicist Charles Augustin de Coulomb defined these electrostatic forces, or Coulombic forces, in the form of a law. According to Coulomb's law, the attractive forces formed between the atoms pull the atoms together, and this action is adversely replicated because of the similar charges between the same ions. This results in a very strong bond of atoms in the crystals. These highly intense forces attribute high melting points and rigid structures to these crystals.

is a weak interaction between the atoms of a

substance, resulting in soft-consistency crystals. The outer orbit of the atoms is completely filled with shared electrons, but their charge keeps transferring.
