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.)
Sodium is a metal. It is a soft, silvery-white metal that is highly reactive and found in Group 1 of the periodic table.
Francium is the most reactive metal in group 1 of the periodic table. It is highly unstable and radioactive, making it difficult to study its chemical properties. Francium reacts violently with water and air, similar to other group 1 metals.
metal
Potassium is the most reactive metal in the fourth period of the periodic table. It is highly reactive due to its low ionization energy, which allows it to readily lose electrons to form positive ions. This reactivity increases as you move down the group.
The right most column, Group 8*, or the noble gases are the least reactive elements in the periodic table these are:platinumgoldmercurythalliumleadbismuthpolonium
Lithium
The least reactive metal in group 1 of the periodic table is francium. Francium is highly radioactive and has a very short half-life, making it extremely rare and difficult to study its chemical properties.
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.
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.
Alkaline metals (Group 1) are the most reactive metals.
The most reactive group of non metal is group-17. It is called halogen family.
The alkali metals in group 1 are the most reactive.
