1.h ( PAPER 2 ) Metalic Bonding Flashcards
1
Q
describe the structure of a metal
A
positive ions surrounded by a sea of delocalised electrons
2
Q
definition of metallic bonding
A
the electrostatic attractions between the positive ions and the electrons
3
Q
why metals good conductors of electricity
A
the delocalised electrons are free ( able ) to move through the structure
4
Q
why are metals good conductors of heat
A
delocalised electrons free to move = energy can be transferred quickly through the material
5
Q
why are metals malleable
A
layers of ions in metal can slide over each other
6
Q
be able to represent a metallic lattice by a 2D diagram
A
???
