Can you identify a metal if you know its density? Explain
It depends upon how accurately the density is determined. In some cases, especially where the "unknown" has a density that isn't close to another metal, yes, the density can identify the metal with a high degree of certainty. In other cases where large groups of metals have the same or nearly the same density, it isn't possibly to identify one in that group with a high degree of certainty. I hope this helps.
