Chemistry - Ionic Bonding

AOS2 Unit1&2

what is ionic bonding

electrons bonding between non metals and metals.

if melting temperatures of two ionic solids is higher than the other, why is the melting point higher than the other?

Because it is due to their electrostatic attraction from their higher chargers, , so it takes more energy to break.

All these solids are brittle and will shatter when a strong force is applied to them.

The ionic bonds in these compounds are strong, but when a force is applied, like charges in the crystal lattice are pushed next to each other, causing repulsion between like charges (positive/positive or negative/negative), which makes the solid shatter.

Are usually crystalline solids..

The property is due to the close-packed, repeating three-dimensional lattice structure.

have high melting and boiling points…

A large amount of energy is required to separate the ions.

are brittle, not malleable…

An external force causes ions with like charges to align and repel.

do not conduct electricity in the solid state

the ions are not mobile.

are often soluble in water….

Water molecules disrupt the crystal lattice, allowing free mobile ions to form.

do conduct electricity in the molten and aqueous states…

The ionic lattice has broken down, allowing the ions to move.

are hard…

The property is due to the strength of the ionic bond.

The brittleness of ionic substances can be best explained ?

Any distortion to the lattice causes repulsion between ions of like charge.

  Ionic substances conduct electricity in the liquid state because they contain…

many mobile cations and anions.
