Suppose an unknown substance has a melting temperature of 1,200 degrees Celsius and a density of 16.7 g/cm3. However, the different individual atoms that make up the element have very different melting temperatures and densities. The unknown substance is most likely a what?
An odd question. Macroscopic concepts such as melting temp, density, cannot be applied to microscopic particles such as atoms.
An atom does not have a melting temperature.
I am wondering if you mistyped the word element here, and should have used instead substance.
Compound may be what you are looking for.
