Is platinum a metal or not?
platinum (Pt), chemical element, the best known and most widely used of the six platinum metals of Groups 8–10, Periods 5 and 6, of the periodic table. A very heavy, precious, silver-white metal, platinum is soft and ductile and has a high melting point and good resistance to corrosion and chemical attack.
Is platinum a metal nonmetal metalloid?
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal.
Is platinum a metal nonmetal or semimetal?
Platinum is a metal. It is the 78th element on the periodic table.
Is platinum a non reactive nonmetal?
Silver, gold, and platinum are metals with the least reactivity. They are found in nature.
Which of the following metal is a platinum metal?
The six platinum-group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits.

Why is platinum non reactive?
Why is it so incredibly unreactive? While it’s true that Pt has two d-bands crossing the Fermi level, the energy gap between the two orbitals is large enough to make the metal very chemically stable.
