Fluorine is the single most reactive nonmetal, with oxygen and chlorine close behind.
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
alkali metals
The most reactive metals are the alkali metals in group 1a.
The most reactive metals of the periodic table are those that belong to alkali group. Among this group, the more electrons contain each atom of each element, the more reactive it is. This is why Francium is the most reactive of alkali metals.
transition metals
No; the noble gas family doesn't contain any metals in it, it only has gases. Also it contains all of the least reactive elements. The most reactive metals are in the alkali metal family, group 1, lithoium , sodium, poatssium etc..
The most reactive non-metals are the halogens, group 17.
fluorine (F)
The elements furthest to the left (alkaline earth metals)
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
The alkali metals (Group 1) and the halogens (Group 17) are the most reactive groups in the periodic table. Alkali metals are highly reactive due to their low ionization energies, while halogens are reactive because of their strong tendency to gain an electron to achieve a full outer shell.
