Lithium - As it is first in Group 1. Group 1 elemts become more reactive as you go down the group.
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.
This is the group 1, the alkali metals.
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.
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.
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.
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.
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
Sodium is a soft, silvery-white, highly reactive metal that belongs to the alkali metal group in the periodic table.
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.
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.
You think probable to caesium (Cs).
