Bonding
There are three types of bonding studied at GCSE:
Ionic bonding
Ionic bonding occurs in that contain a (usually a Group 1 or 2 elements) with a (usually a Group 6 or 7 element). They bond to form .
When forming an ionic compound:
- are transferred from the metal atom to the non-metal atom.
- this forms oppositely-charged .
- the metal ion has a positive charge.
- the non-metal ion has a negative charge.
- an ionic bond is the attraction between these oppositely-charged ions.
- ionic bonding is strong and requires substantial amounts of energy to break.
