What element have the smallest atomic radius?
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.

Which element has the smallest atomic radius hydrogen or helium?
It is hydrogen.
What happens to the size of the atomic radius as you go down the noble gas family?
The atomic radius increase down, from helium to radon.
Which atom has the smallest atomic radii?
Helium has the smallest atomic radius among all the elements on the periodic table. This is because helium has a small number of electron shells and a strong nuclear attraction, which results in a compact atomic structure.
What is the atomic number for helium?
The atomic number of Helium is 2.
What is the atomic size of helium?
The covalent radius of helium is 32 pico meter.
What is the shortest atomic radius of an element?
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius

What element has the smallest radius?
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
What element has the smallest 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
Which element has the smallest atomic radius hydrogen or helium?
It is hydrogen.
Which of the following has the smallest covalent atomic radius LiBeCF?
Helium
Which of these elements has the smallest atomic radius?
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.
What is the atomic radius of helium and how does it compare to other elements in the periodic table?
The atomic radius of helium is about 31 picometers. Helium has one of the smallest atomic radii among all the elements in the periodic table due to its small size and high nuclear charge.
What has the smallest atomic radius out of hydrogen sodium and lithium?
Helium has the smallest atomic radius out of hydrogen, sodium, and lithium. This is because helium has a full electron shell, leading to a smaller effective nuclear charge that pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
What happens to the size of the atomic radius as you go down the noble gas family?
The atomic radius increase down, from helium to radon.
Does magnesium have a smaller radius than helium?
Atoms do not have a radius. A helium atom has a nucleus composed of at least two protons and maybe one or two neutrons. A magnesium atom nucleus (and every other atom on the periodic table other than hydrogen) is BIGGER than a helium nucleus. So if you look at it that way...magnesium is larger than helium
