Ma'am what is Hardness Property??
Dear student
Your question appears to be unclear, assuming it to be hardness property of metals, I am providing an explanation.
Metals are generally solids. We now that the molecules or atoms present in the solid are tightly packed and the molecules are very close to each other.hence this makes the metals very hard and hence they usually have a high density.
Exceptions are : sodium, potassium and mercury
Regards
