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.
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
The elements from the group 12 are not the most reactive chemical elements.
with group 17 elements or halogens
Alkali metals are the elements in the 1st group. In the 1st group,the reactivity of the elements increase down the group. Cs is the most reactive alkali metal.
less reactive.beacuse group-1 elements are the most reactive elements.
it is caesium.
The elements in group 1 become more reactive as you go down the group.
Halogens among halogens fluorine is most reactive
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
The alkali metals group.
yes the most chemically reactive elements are in group 1
The most reactive chemical elements are in the first group of the periodic table of elements.
