the least reactive METAL is lithium!!
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
This is the group 1, the alkali metals.
As you move down the alkali metal group on the periodic table, chemical reactivity increases. This is because the outermost electron in alkali metals is easier to lose as you go down the group, resulting in more reactive behavior with water and air. Lithium is the least reactive alkali metal, while cesium is the most reactive.
The least reactive metal in Group 1 of the periodic table is lithium (Li). While all alkali metals are highly reactive, lithium is less reactive compared to its heavier counterparts, such as sodium, potassium, and rubidium. This reduced reactivity is due to its smaller atomic size and higher ionization energy, which makes it less willing to lose its outermost electron. Consequently, lithium reacts more slowly with water and other substances compared to the other alkali metals.
Florine is a non-metal. It belongs to the halogen group in the periodic table and is highly reactive, forming compounds with many elements.
Lithium
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.

Lithium, (Li) element three and the least reactive of the alkali metals group.
Group 1 or alkali metals
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
This is the group 1, the alkali metals.
This element is francium in the first group of periodic table.
Alkaline metals (Group 1) are the most reactive metals.
The most reactive group of non metal is group-17. It is called halogen family.
The alkali metals in group 1 are the most reactive.
