It is in Group 17 that you will find the most reactive elements. These elements all lack only one electron from having that "magic" electron configuration of the inert gases. That makes these elements very "hungry" to get that "last electron" so their electron structures become more stable.
The elements from the group 12 are not the most reactive chemical elements.
it is caesium.
less reactive.beacuse group-1 elements are the most reactive elements.
The elements in group 1 become more reactive as you go down the group.
Halogens among halogens fluorine is most reactive
yes the most chemically reactive elements are in group 1
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Group 17, the halogens
Group 1 elements are the most reactive among metals, followed by group 2 elements.
group 17 or halogens
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.
Elements are more reactive as you go down the periodic table and to the left.
