I don't think there's a material called tangstain. If you mean tungsten, then tungsten is much harder than platinum.
Diamond is the hardest substance known - but it is not a metal it is an arrangement of carbon atoms in a lattice.
The non metal that has the highest melting point is Carbon. The reason for this is because Carbon has such strong bonds. An example of this would be a diamond.
NO Gold and platinum are not revy reactive.
nothing
Yes, rhodium is a member of the platinum group.
No, I believe platinum is.
Tungsten.

yes, in the sense of durability and resistance to wear and erosion, etc. Gold is durable in some ways but metallurgically softer than element no.78, the grey Stuff, Platinum. they are related. Platinum 78, Gold 79, Mercury, 80 . ( memory jog- Mercury the God of speed- mercury has the highest number of the three- 80 Miles!. that;s going some.
Platinum is a metal because its element category is transition metal.
Platinum is more valuble because it is stronger. White gold is an alloy of gold and at least one white metal. Platinum is a pure metal.
To my satisfaction, Platinum is not classified as a metal
