Metals AS Chemistry

metals tend to have 

• large atoms
• and a high tendency to lose electrons
•  they are the most common elements a 4:1 ratio
• they are in the bottom left of the periodic table

Metallic bonding is

• strong
• only between metal atoms
• you have delocalised electrons in-between and around the metal atoms 
• the positively charged metal ions are attracted to the electrons and if another metal ion is attracted to the same electron a bond is formed

there are 3 metal structures you need to know about 

• hexagonal close packed
• face centred close pack 
• body centred cubic ( not close pack )
• they form giant crystal lattices

the properties of metals 

• high melting points often due to close packing of the ions
• the sea of electrons makes…
