Noble gases have larger atomic radii than alkali metals in the same period.
alkali metals
If alkali metals loses one electron, they achieve the electronic configuration of the nearest noble gases.
Alkali metals are highly reactive and tend to form ionic bonds with other elements, while noble gases are nonreactive and exist as stable, monatomic gases in nature. Alkali metals readily donate an electron to achieve a stable electron configuration, while noble gases already have a full valence shell, making them highly stable and unreactive.

Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
Alkali metals and noble gases
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.
