UNIT 2.4 STRUCTURE OF METALS AND ALLOYS
Chemistry is the study of matter and interactions. Chemistry overlaps with many other sciences.
Below is the contents for this sub unit. This will allow you to jump to any section you desire.
METALLIC BONDING
Metal bonding is represented by positive metal ions in an array and a 'sea of electrons'. The electrons are delocalized allowing them to move freely. This is why metal make great conductors for electricity.
​
INTERSTITIAL ALLOY
​
As you can see from the picture above, small atoms can be incorporated into the metal bond array without disrupting the pattern. This can improve the strength of an alloy or give it other properties.
SUBSTITUTIONAL ALLOY
Sbustitutional alloys replaces an atom with a different one. This again can change the properties of the metal (make it more resistant to rust for example).
