the least reactive METAL is lithium!!
Platinum is the least reactive metal.
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.
Lithium - As it is first in Group 1. Group 1 elemts become more reactive as you go down the group.
the least active metals are at the bottom of the periodic table
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.
The most reactive group of non metal is group-17. It is called halogen family.
