Non-reactive elements or compounds are called inert. This is a bit misleading, however - anything can be made to react given the right circumstances. The noble gases are about as close as you can get to truly inert, but even they will react under extreme conditions.
>>M.T.<<
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
The most reactive non-metals are the halogens, group 17.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Non-reactive elements in the periodic table are typically the noble gases, such as helium, neon, and argon. These elements have a full outer electron shell, making them stable and less likely to form chemical bonds. Reactive elements are those that readily form chemical bonds with other elements, such as the alkali metals (e.g. sodium, potassium) and halogens (e.g. fluorine, chlorine).
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
Group 1 (for metals) and group 17 (for non metals).
The first group of the periodic table consists of alkali metals, which include lithium, sodium, potassium, rubidium, cesium, and francium. These elements have one electron in their outer shell and are highly reactive. They are soft and silvery in appearance.
The most reactive non-metals are the halogens, group 17.
Group 17, the halogens
Elements in group 1 (alkali metals) are typically more reactive with oxygen compared to group 11 (coinage metals). This is because alkali metals have a lower ionization energy and are more likely to form ionic compounds with oxygen.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
The most reactive metals are the alkali metals in group 1a.
Group 1 (metals) and Group 17 (non-metals).
Alkali metals in the first group compose the most reactive family of metals.
These elements are francium and lithium.
The halogens (group 9) and the earth metals (group 1)
