A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
in the Periodic Table it is the most reactive metals!
Alkali metals. This is the most reactive group on 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 Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
Halogens
group 1
group 17, halogens
Chlorine's structure makes it very reactive (it is in group VII of the Periodic Table and therefore needs to gain one electron in order to become stable)!
This element is francium in the first group of periodic table.
The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the Periodic Table, and the halogens are the most reactive...
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
