There is no "group" of metals that are unreactive. However, metals that are low on the reactivity series are unreactive. Examples: Gold, Silver, Titanium
The Noble gasses are a group on the Periodic Table that are largely unreactive.
one reacts and one doesn't
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.
Most metals are reactive to some extent, but their reactivity varies. Some metals, such as gold and platinum, are less reactive and do not easily tarnish or corrode. Other metals, like sodium and potassium, are highly reactive and must be stored in oil to prevent them from reacting with moisture in the air.
The halogens (Group 17) are the most reactive non-metals in the periodic table. They have seven valence electrons and readily gain an electron to achieve a full outer shell, resulting in high reactivity. This group includes elements such as fluorine, chlorine, bromine, and iodine.
The highly reactive non-metals are in the halogen group. They just need one more electron to fill the octet. Therefore they are highly reactive. For example fluorine and chlorine. And the highly reactive metals are placed in the first group (alkali metals). For example Sodium and potassium.
Some are but the most reactive are also non-metals.
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
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.
Metals that are non-reactive are called "inert" metals. Metals like Copper (Cu), Gold (Au), Silver (Ag), and to a certain extent Iron (Fe) are some of the most non-reactive metals on the periodic table. However, Tantalum is usually regarded as the most unreactive metal.
Hydrogen
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.
Halogens.
Fluorine is the single most reactive nonmetal, with oxygen and chlorine close behind.
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.
it describes what are metals, non-metals and what are metalloids (semi-metals) group 1: Alkali Metals (reactive) group 2: Alkaline earth metals (reactive) group 3-12: transition metals group 13-17: non metals group 17: non metal, BUT ALSO a halogen group 18: Noble gases (inert - non reactive) Hope i helped you out, :) Alana
