Group 1 Li, Na, K, Rb, Cs, Fr
Group 1 is the most active and Group 2 is second.
The most active metals belong to Group 1 of the periodic table, known as the alkali metals. This group includes elements such as lithium, sodium, and potassium, which are highly reactive and readily lose electrons to form ions in chemical reactions.
The alkali group of metals is the most active.
Group 1, the Alkali Metals, which are extremely reactive.
These elements are hafnium and zirconium.
The most active metals are alkali metals.The most active nonmetals are halogens.
Most active metals are found on the left side of the periodic table, specifically in groups 1 and 2. These metals have a tendency to lose electrons easily, leading to their reactivity with other elements. Examples include alkali metals like lithium, sodium, and potassium.
In the Periodic Table they are found in Group (I). They are lithium, sodium , potassium , rubidium, caesium and francium. They become explosive on going down the group. Also francium is also radio-active. None of these metals are found 'native' on Earth. They all ionise and are found in other chemicals/substance on Earth. .e.g SALT Sodium chloride.
Alkali MetalsLithium, potassium and sodium are considered to be some of the most active metals.
These elements are hafnium and zirconium.
The most active metals, including alkali metals and alkaline earth metals, are located in groups 1 and 2 of the periodic table, respectively. Alkali metals are in group 1, while alkaline earth metals are in group 2. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
The group I metals (Lithium, Sodium, Potassium, etc.) are very well known for their extreme reactivity. These metals will tarnish quickly in air and can cause small detonations when thrown into water via a highly exothermic reaction that produces flammable hydrogen gas.
