How can an atom become positive?
By losing electrons
How can an atom become negative?
By gaining electorons
What is an ionic bond between?
A metal and a non-metal (ions of opposite charges)
What diagram do you draw to show an ionic bond?
A dot and cross diagram
What is in a dot and cross diagram?
The atoms show in the transfer of electrons and the ions in brackets
What is a covalent bond between?
It is between non-metals
What does the diagram showing covalent bonding look like?

How are electrons spread out in a covalent bond?
They are shared in pairs
What is a lone pair?
A pair of electrons that is not shared
What is metallic bonding between?
Just metals
What is the diagram for metallic bonding like?
Ions with their charge in a sea of delocalised electrons
How is an ion delocalised?
It is not connected to an atom
What does diatomic mean?
Two atoms covalently bonded in the molecule
What does molecule mean?
