properties of metals and alloys including conduction.

Question 1

what are the properties of metallic bonds and what does this mean that they are useful for?

Answer 1

very strong so most metals have high melting and boiling points.
structural materials.

Question 2

what can the delocalised electrons do and what does it mean?

Answer 2

move around freely and transfer energy.
good thermal and electrical conductors.

Question 3

what arrangement do the particles in pure metals have?

Answer 3

regular arrangement.

Question 4

what are the layers able to do and what does it mean?

Answer 4

slide over each other quite easily.
bent and shaped.

Question 5

what are most metal objects made out of?

Answer 5

alloys.

Question 6

what is an alloy?

Answer 6

mixtures that contain a metal and at least one other element.

Question 7

why aren’t pure metals suited for different uses?

Answer 7

too soft.

Question 8

what happens in the particle arrangement of alloys that allow it to be stronger and harder than pure metals?

Answer 8

added element disturbs the regular arrangement of the metal atom so the layers do not slide over each other so easily.
