Ionic Bonding

Ion =) ion are formed when electrons are transferred from one atom to another atom. Electrons are either gain or lost to gain a full outer shells ( 2 or 8 )

Ion Bonding =) when atoms are held together in a lattice by electrostatic forces, between a metal and one non-metal.

Ion compound =) When oppositely charged ion come together and form ionic bonds.

Compound ion =) Ions that are made up of groups of atoms with an overall charge.

Electrostatic attraction =) A forces that holds positively and negatively charged ions together.

Positively charged ion =) Cations

Negatively charge ion =) Anions

Giant Ionic lattice

Ionic crystal are giant lattice of ions

A lattice is a regular structure, made up of the same basic unit repeated over.

An ionic lattice are a type of crystal structure, a. Regality arrangement of atoms in a solid / liquid lattice

The structure of the ionic compound decides their physical properties :

Electrical conductivity

Ionic compound can only conduct electricity when they are molten. the ions are able to move freely + carry a charge

Melting point

Ionic compound has an extremely high melting point due to the giant ionic lattice that are held by very strong electrostatic forces.

These forces take loads of energy to break.

Solubility

Ionic compound tend to dissolved in water.

Water molecules = polar ( some positive + some negative charge molecules)

The water molecules pulls the ion away from the lattice = cause to dissolve
