what makes it more malleable?
By alloying it with gold, dissolving the alloy in hot "aqua regia", precipitating the platinum with ammonium chloride, igniting the ammonium chloroplatinate, and hammering the resulting finely divided platinum to make it cohere.

where are the heaviest metals located in a periodic table Columns 3 to 16 which are some of these found in the environment? Iron, copper, tin, silver, gold, and platinum. what are the physical properties of the last element? It has excellent resistance to corrosion, is stable at high temperatures and has stable electrical properties. which country was the first to discover it? UNANSWERABLE do people invest in it? Yes, as it finds use in jewellery, usually as a 90–95% alloy, due to its inertness.

Platinum [SEP] Means of malleability
Carl von Sickingen researched platinum extensively in 1772. He succeeded in making malleable platinum by alloying it with gold, dissolving the alloy in hot "aqua regia", precipitating the platinum with ammonium chloride, igniting the ammonium chloroplatinate, and hammering the resulting finely divided platinum to make it cohere. Franz Karl Achard made the first platinum crucible in 1784. He worked with the platinum by fusing it with arsenic, then later volatilizing the arsenic. Because the other platinum-family members were not discovered yet (platinum was the first in the list), Scheffer and Sickingen made the false assumption that due to its hardness—which is slightly more than for pure iron—platinum would be a relatively non-pliable material, even brittle at times, when in fact its ductility and malleability are close to that of gold.
