Question

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

Answer 1

Answer:

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.

Answer 2

Explanation:

Noble gases are the group 18 gases (helium, neon ,argon ,krypton , xenon) which are non reactive as they have their octet compete (duplet in case of Helium)

USES:-

1.Helium is used in filling air in footballs

2.Argon gas is used in bulbs

Noble Metals are Silver , Gold , platinum as they are very less reactive

USES :-

Gold and silver is used in jewellery
