The first cloumn in the Periodic Table has the most reactive elements. The elements decrease in reactivity as you go across the table.
in other words alkali metals
Alkali
Yes
The most active non metals are the halogens, located in group XVII. They are the most active non-metals because they only need 1 electron to make their outer shell complete.
alkaline metals, alkaline earth metals, lanthanides and actinides and metals in mixed groups
Because Hydrogen behaves unlike most of the other groups, but has characteristics of Groups 1 and 17 . It can form alloys with metals (like group 1)
The three most general elemental groups are nonmetals, semimetals, and metals. The characteristics you've described fit the "metals" group of elements.
The alkali group of metals is the most active.
The most active elements are in group one and two on the periodic table and are always found in nature combined with other elements. The most active metals are in group one, which is the alkali metals, they wouldn't be in group two. (if you need more information) http://www.chem4kids.com/files/elem_alkalimetal.HTML
Alkali MetalsLithium, potassium and sodium are considered to be some of the most active metals.
Alkali metals are the most reactive metals.
The most active metals are alkali metals.The most active nonmetals are halogens.
metals & non-metals
Group 1 metals or alkali metals
the most obstrobvious metals are locationated in the lastetic row on the periocictia tablerama
The most reactive groups are alkali metals and halogens.
1. alkaline metals 2. alkaline earths metals
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
Metals. The two most reactive groups of metals that readily form these bonds with nonmetals are the alkali metals and the alkaline earth metals. Groups 1A and 2A.
