Metallic bonding + properties

Question 1

what are the properties of metals

Answer 1

they conduct electricity
conduct heat
malleable
ductile
high melting points

Question 2

how does metallic bonding look

Answer 2

a lattice of + metal ions
surrounded by delocalised electrons

Question 3

How are high melting points related

Answer 3

bonds within metals are strong because they have strong electrostatic forces of attraction between + metal ions and surrounding delocalised electrons

Question 4

How is electrical conductivity related

Answer 4

electrons in metallic bonding are delocalised which means they can carry a charge throughout the strucutre
A flow of electrons is a current and they can transfer heat energy too

Question 5

How is malleability related

Answer 5

metals can be pressed into new shapes and when you remove the force it remains in the new shape
Layers of metal ions can slide past one another and when force is removed the electrons hold the metal ions in shape

Question 6

How is ductility related

Answer 6

Metals can be stretched into wires - layers of metal ions can slide past one another until they are longer and thin
when the stretching force is removed delocalised electrons quickly re-form metallic bonds
