Lithium is NOT the most active alkali metal. Francium is the most active but is available in such trace quantities and radioactive that for practical purposes it is Cesium that is considered most active.
What else can I help you with?
What is a less active alkali metal?
A less active alkali metal refers to those elements in Group 1 of the periodic table that are less reactive than their counterparts, such as lithium (Li), sodium (Na), and potassium (K). Among the alkali metals, lithium is generally considered the least reactive, followed by sodium. The reactivity of alkali metals increases down the group, so francium (Fr) is the most reactive, while lithium exhibits the least vigorous reactions with water and other substances.
What alkali metal reacts most slowly with water?
Lithium (Li) is the alkali metal that reacts most slowly with water. It is the first alkali metal and thus, the least reactive of the group. The lithium metal is seen to dart around the surface of the water with some whzzing and effervescence of hydrogen gas. The heat produced from the reaction may not be sufficient to ignite the hydrogen gas, resulting in no flame, compared to other metals like sodium and potassium where the reaction would be more violet and the metal would quickly catch fire.
What state are most alkali metals?
Most alkali metals are found in solid state at room temperature, except for the lightest alkali metal, lithium, which is a soft metal. Alkali metals are highly reactive and easily lose their outermost electron to form positive ions.
Where are the most active metals located-?
Alkali MetalsLithium, potassium and sodium are considered to be some of the most active metals.
What group would lithium be in on the periodic table?
They are in group one called the Alkali Metals.Those are alkali metals. They are the most reactive of all the metals, and they are in group 1 of the periodic table, all the way to the left.

Which element is the most active metal?
Potassium is the most active metal. It is highly reactive and can easily react with water to produce hydrogen gas and caustic potassium hydroxide.

What alkali metal is most reactive out of cesium lithium potassium and sodium?
Reactivity increase down the group.Ceasium is the most reactive.

If you mix chlorine lithium and nickel together which two elements would be the most reactive?
Chlorine and lithium would be the most reactive because chlorine is a halogen and lithium is an alkali metal, both of which are highly reactive elements. Nickel is a transition metal and is less reactive compared to chlorine and lithium.
What group would lithium be in on the periodic table?
They are in group one called the Alkali Metals.Those are alkali metals. They are the most reactive of all the metals, and they are in group 1 of the periodic table, all the way to the left.
What alkali metal compounds are used in the treatment of bipolar disorder?
Lithium salts, such as lithium carbonate and lithium citrate, are commonly used in the treatment of bipolar disorder. These compounds help stabilize mood and reduce symptoms of mania and depression in individuals with bipolar disorder.
Which Alkali metals would undergo the least exothermic reaction with chlorine?
Cesium would undergo the least exothermic reaction with chlorine among the alkali metals. This is because cesium is the most reactive alkali metal, so it requires more energy to form a compound with chlorine compared to the other alkali metals.
What is most active metal of the calcium family is?
The most active metal in the calcium family is francium. It is the least stable alkali metal and can react violently with water, making it extremely rare and highly radioactive.
Is francium an alkali metal?
Yes, francium is an alkali metal; the group contain lithium, sodium, potassium, caesium, rubidium and francium.
