Why gold and platinum are called noble metals?
Because they don't react with other elements.
Do metal react or do not react?
It depends on the specific metal and the conditions. Some metals, like alkali metals, are highly reactive and will react readily with air or water. Other metals, like gold or platinum, are much less reactive and do not readily react under normal conditions.
Name metals which do not react with oxygen?
Au and Pt are some metals which do not react with O.
Do all metals react with hydrochloric acid to give hydrogen gas?
No, not all metals react with hydrochloric acid to produce hydrogen gas. Only metals higher in the reactivity series than hydrogen, such as zinc, iron, and magnesium, will react with hydrochloric acid to form hydrogen gas. Metals like gold, silver, and platinum do not react with hydrochloric acid.
Are gold and platinum reactive metals?
Gold and platinum are both considered noble metals because they are resistant to oxidation and corrosion, making them relatively unreactive compared to other metals. However, platinum can react with certain strong oxidizing agents under extreme conditions. Gold, on the other hand, is highly unreactive and does not tarnish or corrode easily.
Is platinum heavy compared to other metals?
Yes, platinum is heavy compared to other metals.
What is reactivity of properties of metals?
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
What is the metallic properties?

What does silver not react with?
Silver does not react with oxygen or water, making it resistant to tarnishing. It also does not react with most acids, except for nitric acid. Additionally, silver is relatively unreactive with other metals such as gold and platinum.
What metals don't react with hydrochloric acid?
Metals such as gold, platinum, and silver do not react with hydrochloric acid due to their inert nature. They form a protective oxide layer on their surface that prevents them from reacting with acids.
This metal does not react with water?
Examples: platinum metals, gold, silver, lead, etc.
Would sodium hydroxide solution react with platinum or gold?
Sodium hydroxide solution will not react with platinum or gold. Platinum and gold are noble metals that are resistant to corrosion by most chemicals, including sodium hydroxide.
