Probable lanthanum.
The chemical reactivity (and electronegativity) are very similar for lanthanoids. This explain the difficulties of identification and separation.

What is the most reactive metal in group 1 of the periodic table?
Frankium :]
The most reactive nonmetals on the periodic table are?
The most reactive nonmetals are the halogens in group 17 of the periodic table.
what is the most reactive (non-metals) group in the periodic table?
the most reactive (non-metals) group in the periodic table is GROUP 17+they are all reactive
Where are the most reactive element found on the periodic table?
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.
Where are most reactive metals located?
At the left, especially the lower left, and at the right, especially the upper right, of a hypothetical periodic table that is the same as the standard periodic table except for omitting the noble gases.
What is the most reactive group of metals in the periodic table is the?
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
Least reactive metal in group 1 of the periodic table?
the least reactive METAL is lithium!!
What family of the most reactive group of metals 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.
Where is the most reactive metal on the periodic table located?
This element is francium in the first group of periodic table.
What is the least reactive metal in group one of the periodic table?
Lithium
What is the most reactive metal group in the periodic table?
Group 1 or alkali metals
What is the most reactive metal in group 1 of the periodic table?
Frankium :]
What metal family is the most reactive in the periodic table?
Alkaline metals (Group 1) are the most reactive metals.
What is the most reactive metal and nonmetal group in the periodic table?
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
What are the most reactive groups of nonmetals on the periodic table?
The most reactive group of non metal is group-17. It is called halogen family.
What metal in the far-left-column of the periodic table that are extremely reactive?
The alkali metals in group 1 are the most reactive.
What group is 1?
in the Periodic Table it is the most reactive metals!
