In the same period what have large atomic radii alkali metals or noble gases?
Noble gases have larger atomic radii than alkali metals in the same period.
Which elements has the largest atomic radii in periodic table?
The atomic radii of members of the Group 1A (Alkali metals), increases down the group. Therefore Francium has the largest atomic radius of the Alkali metals. However Fr has no stable isotopes, thus is not naturally occurring. So Cs-133 is the largest you can find.
Why do alkali metals have a low density?
Alkali metals have a low density because they have a single valence electron that is loosely held, leading to larger atomic size and lower atomic mass. This results in a less compact arrangement of atoms, contributing to the low density observed in alkali metals.
What are more reactive alkali metals or alkline earth metals?
alkali metals
What family of elements is in the leftmost column?
alkali metals

Characteristics of alkali metals?
Alkali metals are group 1 elements in the periodic table, including lithium, sodium, potassium, rubidium, cesium, and francium. They are highly reactive, silvery-colored metals that are soft enough to be cut with a knife. Alkali metals have one electron in their outermost energy level, making them eager to lose that electron to form a +1 cation.
What group of elements have members of the smallest atomic radii for a given period?
The group of elements with members of the smallest atomic radii for a given period is the group of noble gases. Noble gases have the smallest atomic radii because they have a completely filled valence shell, which results in strong electron-electron repulsions and a smaller atomic size.
Are alkalai metals metal?
According to the scientific definition of a metal yes, Alkali metals are considered metals, but it is important to understand that alkali metals have different properties from regular metals. The alkali metals exhibit many of the physical properties common to metals, although their densities are lower than those of other metals. Alkali metals have one electron in their outer shell, which is loosely bound. This gives them the largest atomic radii of the elements in their respective periods. Their low ionization energies result in their metallic properties and high reactivities. An alkali metal can easily lose its valence electron to form the univalent cation. Alkali metals have low electronegativities. They react readily with nonmetals, particularly halogens.
How chemically active are alkali metals?
Alkali metals are the most reactive metals.
What are more reactive alkali metals or alkline earth metals?
alkali metals
Is alkali the only earth metal?
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
How are alkali metals different any from other metals?
Alkali metals are very reactive metals.
How do alkali metals react with other alkali metals?
They don't
Why are earth alkali metals called earth alkali metals?
Alkali earth metals are named after their oxides, alkaline earth.
