In lab we tested the heat capacities of aluminium, tin, copper and lead



Now we are asked to make molecular level explanations.

Any ideas?

[Arkcon]

How do they differ from one another, on the atomic and molecular (if that actually applies to a pure metal) level?  What sort of differences do bulk pure materials have from one another?

Are you thinking something like mass or the number of protons?

Or something more?

[Arkcon]

No, I wasn't really going for protons, 'tho you should consider molecular mass.  There is also another bulk property of each metal worth considering.

Ok, I took care of mass.

How about charge?
Density?
Atomic radius?
