This is not correct the best answer for helium would be 0.0 or n/a
Helium also has no covalent radius.
The atomic volume of helium is 31.8
28 picometer

It is hydrogen.
The atomic radius increase down, from helium to radon.
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

Fluorine has the smallest atomic radii because it is towards the right of the periodic table and on top.
133 what? what are the units here? err.....i suppose its tht of Fluorine's......hey, if u find out if flourine's atomic radius is more thn tht of helium's, jus lemme know. thnq
The covalent radius of helium is 32 pico meter.
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm

The answer choices for this question wasn't provided. Oxygen has the smallest atomic radius. The higher the electronegativity in an element makes the atomic radius smaller.
From group 17 (7A), fluorine has the lowest atomic radius.
Fluorine has the smallest atomic radii because it is towards the right of the periodic table and on top.
