Lithium - As it is first in Group 1. Group 1 elemts become more reactive as you go down the group.

Francium is the least reactive metal in the alkali metal group. This is due to its large atomic size and low electronegativity, which result in weaker attraction to electrons and less reactivity compared to other alkali metals. However, francium is extremely rare and radioactive, making it difficult to study its chemical properties.

How does the chemical reactivity to alkali metal vary?
As you move down the alkali metal group on the periodic table, chemical reactivity increases. This is because the outermost electron in alkali metals is easier to lose as you go down the group, resulting in more reactive behavior with water and air. Lithium is the least reactive alkali metal, while cesium is the most reactive.
In what group is the most reactive metal located on the periodic table?
This is the group 1, the alkali metals.
Is sodium is a noble gas?
No, sodium is not a noble gas. It is a reactive metal that belongs to the alkali metal group in the periodic table. Noble gases are a group of non-reactive elements that include helium, neon, argon, krypton, xenon, and radon.
Is iodine an alkali metal?
No, iodine is not an alkali metal. Iodine is classified as a halogen, a group of elements that are highly reactive nonmetals. Alkali metals are a separate group of elements that include lithium, sodium, and potassium.
Which is the hardest metal in group 1 that is in alkali metals?
Francium is considered the hardest metal in Group 1 (alkali metals). It is the most reactive alkali metal and is very rare in nature. Due to its high reactivity and radioactive nature, it is challenging to study and handle francium.
Which group is the most highly reactive metal group?
Group 1, the Alkali Metals, which are extremely reactive.
Is lithium a alkaline earth metal?
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
Why is Francium the most reactive alkali metal?
because it has the most number of electrons in the alkali metal group
What is the lightest metal in th periodic table of elements?
Lithium, (Li) element three and the least reactive of the alkali metals group.
What is the most reactive metal group in the periodic table?
Group 1 or alkali metals
In what group is the most reactive metal located on the periodic table?
This is the group 1, the alkali metals.
What metal is expected to be least reactive gold potassium sodium or lithium?
Gold. The other three, as Group 1 alkali metals, are highly reactive.
What is the difference between sodium and aluminum'?
Sodium is a highly reactive alkali metal whereas aluminium is a less reactive metal in the boron group.
Least reactive alkaline earth metal?
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
What is the most reactive group of metals in the periodic table is the?
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
What are the 5most reactive elements in the alkali metal group?
You think probable to caesium (Cs).
Is iodine an alkali metal?
No, iodine is not an alkali metal. Iodine is classified as a halogen, a group of elements that are highly reactive nonmetals. Alkali metals are a separate group of elements that include lithium, sodium, and potassium.
