Question

Write are noble metals and noble gases? Write their uses also.
​

Answer 1

Answer:

Noble metals are those that have outstanding resistance to oxidation, even at high temperature. The grouping of such metals is not well defined but usually includes rhenium, ruthenium, rhodium, palladium, silver, osmium,iridium, platinum and gold that is the metals of VIIb,VIII, and Ib of the second and third transition series of the periodic table.

Noble gases the ones in the last period of the periodic table. helium, neon, argon, krypton, xenon, organesson. They have similar properties. Odorless, colourless, monoatomic gases with low chemical reactivity. They have completely filled outermost electronic shell.

Answers;

Noble metals

The noble gases (historically also the inert gases; sometimes referred to as aerogens[1]) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is variously predicted to be a noble gas as well or to break the trend due to relativistic effects; its chemistry has not yet been investigated.

Noble metal

In chemistry, noble metals are metallic elements that show outstanding resistance to chemical attack even at high temperatures.[8] They are well known for their catalytic properties and associated capacity to facilitate or control the rates of chemical reactions.[8] The short list of chemically noble metals (those elements upon which almost all chemists agree)[citation needed] comprises ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), platinum (Pt), and gold (Au).[9] In periodic table terms the noble metals correspond to the noble gases.[10]
