Is a alkali metal that can be cut with a knife?
Most of the Alkali metals are soft enough to be cut with a knife, certainly Sodium, Potassium and Rubidium are.
Which elements is most reactive alkali metals or alkali earth metal or carbon family or inert gases?
alkali metals
Why the lithium is the most active alkali metal?
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 is the most reactive alkali earth metal?
The most explosive alkali earth metal on the planet is Francium. No actually Francium is still below Cesium. And Cesium is the second explosive on the planet. No one actually knows what the most explosive alkali metal is because they are not legally allowed to test it.
Which alkali metal is the most reactive on the periodic table?
Hydrogen.
Why is Francium the most reactive alkali metal?
because it has the most number of electrons in the alkali metal group

What alkali earth metal is the most reactive Be or Sr?
Sr
Which alkali metal is the most reactive on the periodic table?
Hydrogen.
Is sodium a halogen a noble gas a alkali metal or a alkaline earth metal element?
It is located, in the periodic table, with the metalloids. However, it is a transition metal.
