at the bottom of tne first group.
The most reactive metal on the table is Caesium. Fluorine is the most reactive non-metal on the table. For metal periods, reactivity decreases from left to right. Non-metals are the opposite.
The halogen chlorine and the reactive metal sodium are in table salt.
Sodium is a metal. It is a soft, silvery-white metal that is highly reactive and found in Group 1 of 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
Francium is the most reactive metal.
fluorine is the most reactive non metal in the periodic table.
Oxygen is a non-metal. It is a reactive gas that is essential for sustaining life and is found in the non-metal group on the periodic table.
SODIUM
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
Francium (Fr)
Hydrogen.
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.
