metals have giant metallic structures composed of a lattice of cations surrounded by a sea of delocalised electrons
2
Q
what is the conductivity?

able to conduct
3
Q
explain the conductivity?
A
mobile delocalised electrons
4

A
TRUE - because layers can slide
5
Q
what is an alloy?
A
a combination of two or more metals or a metal and a non metal such as carbon.
6
Q
How do the properties of an alloy differ to pure metals?
