Ionic compounds have high melting/boiling point due to the strong electrostatic forces of attraction, which require a large amount of heat energy to overcome.covalent bonds may be stronger than the attraction between two ions, but in ionic compounds there are attractions in all directions.

They contrast to the characteristics of a covalent bonds.

Ions exert electrostatic force on each other. However, in a liquid state or when dissolved in water, they will conduct electricity well because the ions are free to move and can carry charge. Ionic compounds, such as sodium chloride (NaCl), are formed by a transfer of electrons that creates ions.

In a solid state they do not conduct electricity. Formation of Ions An ion is an electrically charged atom or group of atoms formed by the loss or gain of electrons This loss or gain of electrons takes place.

Ionic compounds are soluble in water as the ions form favorable interactions with water molecules which release sufficient energy to break away from the lattice.

Three dimensional ionic structure called a giant ionic crystal lattice structure.

Both ions are now oppositely charged and they are held by strong electrostatic forces of attraction.

Chlorine atoms gain the electrons from the sodium atoms to form negatively charged chloride ions (Cl -). First, sodium atoms (Na) oxidize and lose an electron to form positively charged sodium ions (Na +). This occurs, for example, when sodium and chlorine join to form common table salt, NaCl. A non-metal atom becomes a negative anion as it gains electron(s). A maximum of three electrons can be transferred in the process.Ī metal atom becomes a positive cation because it loses electron(s). The greater the difference in charge between the metal and non-metal ion, the stronger the ionic bond. This happens after a metal atom loses one or more of its electrons to the non-metal atom. This occurs when charged atoms ( ions) attract. An ionic bond is the electrostatic forces of attraction between a non-metal and a metal ion in a giant ionic crystal lattice.
