metals and covalent lattices

Question 1

describe metallic bonding

Answer 1

caused by electrostatic attraction between cations and e- which have been lost.
they group in a sea of delocalised e- and attraction force overrides repulsion force
metal cations are arranged within a lattice

Question 2

electricity

Answer 2

movement of charged particles i.e electrons

Question 3

explain how metalic bonding links to ability to conduct heat and electricity

Answer 3

cations in a sea of delocalised e- held together by electrostatic forces
these e- are free moving allowing electricity to move through the lattice. they also allow therman energy to be dispersed via the lattice

Question 4

explain why metals are malleable and ductile

Answer 4

metals have a sea of delocalised e- that are able to shift when the lattice is altered, amintaining electrostatic force of attraction. therefore, shape changes without breaking or cracking.

Question 5

describe the strength of metallic bonding

Answer 5

due to strong electro force of A, metals are very hard as the cations are held togheter tightly in teh lattice. leads to metals being tightly packed, macking them very dnese.

Question 6

describe how copper atoms would interact to form metallic bonds

Answer 6

first it would eject its electrons to form cu2+. this forms a sea of delocalised electorns. the electrostatic force of attraction between teh e- and the cations arrange itself into a lattice structure/
