Resumen del Recurso
Bonding
Ionic Bonding
Metals and Non-Metals
Electrons go from Metal to Non-Metal
Mg + O -->MgO
Ions are created, not Atoms
Ions are Charged Atoms
Metal
Posotive
Lost Electrons
Non-Metal
Negative
Gained Electrons
Opposites Attract
So the opposite charge of the Ions attract each other
Covelent Bonding
Non-Metals only
They share electrons
Can have single or double bonds
Double are stronger
Giant Covelent Structures
Graphite
Each Carbon Atom is only bonded to 3 others
Free Electons
Layerd in structure
Conducts Electrisity
Free Electrons
Silcone Dioxide
Very High melting point
Semi-conductor
Similar Structure to diamond
Diamond
Each Carbon is bonded to 4 other Atoms
Very high melting point
Very hard
Due to really strong bonds
Does not conduct electrisity
Graphite, Diamond and Silicone Dioxide
The sharing keeps them bonded
Attracted Together
Metalic Bonding
Metals Only
Examples would be Copper
De-localised Electons
Form a "Sea of Electons"
Acts like glue to keep the posotive Metal Ions attracted
What makes Metals Shiny
This conducts electrisity
The de-localised electrons carry the charge
Forms layered (lattice) structure
Can slide over each other
Malleable
However, in Alloys, this does not happen
An Alloy is a mixture of Metals
Makes it more brittle
