Francium is considered the most reactive of the group 1 elements. This is because it is the largest of all elements in group 1, therefore takes the least amount of energy to lose an electron (Group 1 elements react by losing electrons.)
As you go down in group 1, the reactivity of the elements increases, so sodium is more reactive than lithium.
Technically, the most reactive group 1 element is francium.
However, due to its extreme rarity and short half-life, the titel is often given to cesium.
Sodium (Na) is the least reactive. It will still react violently, but not as badly as the other alkali metals (group 1). The most reactive is Francium.
The element Hydrogen. Elements become more reactive as you move down in a group.
beryllium is the least reactive element
Lithium.
Lithium

The right most column, Group 8*, or the noble gases are the least reactive elements in the periodic table these are:platinumgoldmercurythalliumleadbismuthpolonium
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
fluorine is the most reactive non metal in the periodic table.
The Alkali metals are the most reactive group of metals in the periodic table. Of these Francium is the most reactive metal of all.
the least reactive METAL is lithium!!
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.
Platinum is the least reactive metal.
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.
Frankium :]
Alkaline metals (Group 1) are the most reactive metals.
