Covalent bond
How can you tell if it is ionically or covalently bonded?
How are compounds formed?
Ionic Bonding
Covalent bonding
Losing electrons forms positive ions
(because there are now more protons)
The formula of an ionic compound shows the ratio of ions present
Remember.....
Many substances containing covalent bonds are simple molecules but they can make giant covalent structures too.
The atoms in metals are formed in a regular pattern, layer upon layer.
Metallic bonding
(an example of a giant structure)
