Because they do not conduct electricity
<><><>
Sorry- above answer is DANGEROUSLY incorrect- ALL metals conduct electricity- gold and silver especially. However, non-reactive metals do not tarnish or rust- they stay pretty.
Group-17 are most reactive non-metals. They form halogens.
Hydrogen
Some are but the most reactive are also non-metals.
Halogens.
Most non-metals are not highly reactive or an completely inert. However, the Halogens in Group 17 are reactive with nearly every substance on the planet.
Gold is considered a non-reactive metal because it is very unreactive with most substances. It does not tarnish or corrode easily, which is why it is often used for jewelry and other applications where long-term stability is desired.
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
the very non reactive elements are very valuable but they are platinium, gold and silver.
one reacts and one doesn't
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
Group-17 are most reactive non-metals. They form halogens.
Non-metals do not show displacement reactions because they are less reactive than metals. Displacement reactions occur when a more reactive element displaces a less reactive element from its compound. Since non-metals are not as reactive as metals, they are not typically displaced in reactions.
Hydrogen
A non-reactive metal is a metal that does not easily undergo chemical reactions with other substances, such as air or water. Examples include gold, silver, and platinum. These metals are often used for jewelry or in industrial applications where high resistance to corrosion is needed.
