The substance has a dnesity of 96.5/5=19.32 g/c.c.Metals in this range of densities could be
Uranium 18.95
Tungsten 19.25
Gold 19.282
Roentgenium 19.282+
However, Uranium in this form is rarely found free in nature.
Roentgenium exists in laboratories.
Tungsten is hard and has a high melting point.
Gold is frequently found in nature, and can be distinguised by its gold colour.
So check the appearance, colour, and refine the accuracy of the density measurement before concluding it is gold.
