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.
Hydrogen. It is proportional to the atomic weight of an element
Hydrogen :) !
Chlorine
Br, or bromine.
Helium at 31 picometers.
Hydrogen (110 pm) and helium (140 pm).
Br (Apex 2021)
hydrogen
Chlorine
Br
Chlorine will have the smallest atomic radius, bromine the largest.
Noble gases have the smallest atomic radius.
atomic radius increases as you go down the group and decreases as you go across the period therefore the smallest atomic radius for group 14 is carbon.
Argon is the atom that has the smallest radius in Period 3. As you go cross Period 3 from left to right, the atomic radii of the elements decrease. The elements in Period 3 from left to right begin with sodium and ends with argon.
N, P, As and Sb
Chlorine will have the smallest atomic radius, bromine the largest.
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
Flourine and Phosphorous.
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.

Noble gases have the smallest atomic radius.
Hydrogen has the smallest atomic radius - 25 pm.
it's neon
atomic radius increases as you go down the group and decreases as you go across the period therefore the smallest atomic radius for group 14 is carbon.
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
Lithium(520)
Argon is the atom that has the smallest radius in Period 3. As you go cross Period 3 from left to right, the atomic radii of the elements decrease. The elements in Period 3 from left to right begin with sodium and ends with argon.
