The force holding atoms together.
Holds oppositley charged ions together.
Oppositley charged ions form a bond and on atoms tranfers electrons to another.
Giant Lattice Structure
Structure ions are held in.
The arrangment of ions maximises the attractive force between oppositley charged ions and minimises the replusion between similarly charged ions.
Giant lattice of ions form ionic crystals.
They have the same number of arrangement of electrons.
E.g. Na+ and Ne.
1s2 2s2 2p6
When an element reacts, it does so in a way that results in an outer shell containing eight electrons.
The radius of an ion in a crystal.
The radii of a positive ion is smaller than the element's atomic raduis because the remaining electrons are closer to the nucleus.
Negative ions are larger than the elements atomic radius.
The enthalpy of formation of one mole of an ionic compound from gasous ions under standard conditions.
The sharing of electrons between two atoms.
Dative Covalent Bond
Both electrons that make up the covalent bond are from the same atoms.
Strong attraction between the positive metal ions and the sea of delocalised electrons the sea that surrounds them.
Metals are good conductors of heat and electricity.
