Lithium - As it is first in Group 1. Group 1 elemts become more reactive as you go down the group.
Li
the least reactive METAL is lithium!!
This is the group 1, the alkali metals.
The alkali metals are the most reactive of all groups on the periodic table. Some of the metals are lithium, potassium and sodium.
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.
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
Group 1, the Alkali Metals, which are extremely reactive.
because it has the most number of electrons in the alkali metal group
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
Lithium, (Li) element three and the least reactive of the alkali metals group.
Group 1 or alkali metals
the least reactive METAL is lithium!!
Alkali metals are the elements in the 1st group. In the 1st group,the reactivity of the elements increase down the group. Cs is the most reactive alkali metal.
This is the group 1, the alkali metals.
Gold. The other three, as Group 1 alkali metals, are highly reactive.
Sodium is a highly reactive alkali metal whereas aluminium is a less reactive metal in the boron group.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
You think probable to caesium (Cs).
