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.)
The least reactive metal in Group 1 of the Periodic Table is francium. Francium is a highly radioactive and rare element that has very little practical use due to its extreme reactivity with other elements.
As you go down in group 1, the reactivity of the elements increases, so sodium is more reactive than lithium.
Technically, the most reactive group 1 element is francium.
However, due to its extreme rarity and short half-life, the titel is often given to cesium.
Sodium (Na) is the least reactive. It will still react violently, but not as badly as the other alkali metals (group 1). The most reactive is Francium.
The element Hydrogen. Elements become more reactive as you move down in a group.
beryllium is the least reactive element
Lithium.
Lithium
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.
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.
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.
The least reactive metals are typically found in Group 18 of the periodic table, known as the noble gases. These elements have a full outer electron shell, making them very stable and unreactive. They include helium, neon, argon, krypton, xenon, and radon.
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.
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.
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.
Alkaline metals (Group 1) are the most reactive metals.
