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.
Lithium has the smallest atomic radius among the elements listed.
Among bromine, sulfur, chlorine, and selenium, chlorine has the smallest atomic radius. This is because atomic radius decreases as you move from left to right across a period on the periodic table. Chlorine is located on the right side of the periodic table in the 17th group, which indicates smaller atomic radius.
The element with the smallest atomic radius among Ge, Se, Br, and As is Arsenic (As). Atomic size generally decreases across a period from left to right, so the elements in this group progress in order of increasing atomic radius: Germanium (Ge) > Selenium (Se) > Bromine (Br) > Arsenic (As).
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.
Fluorine has the smallest atomic radius among fluorine, oxygen, and chlorine. Oxygen has a larger atomic radius than fluorine but smaller than chlorine. Chlorine has the largest atomic radius among the three elements.
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
Fluorine has the smallest atomic radius, while Francium has the largest 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.

Lithium has the smallest atomic radius among the elements listed.
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
Among bromine, sulfur, chlorine, and selenium, chlorine has the smallest atomic radius. This is because atomic radius decreases as you move from left to right across a period on the periodic table. Chlorine is located on the right side of the periodic table in the 17th group, which indicates smaller atomic radius.
Fluorine has the smallest atomic radius of all the p-block elements. This is because as you move across a period from left to right, the atomic radius decreases due to increasing nuclear charge pulling the electrons closer to the nucleus.
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
The element with the smallest atomic radius among Ge, Se, Br, and As is Arsenic (As). Atomic size generally decreases across a period from left to right, so the elements in this group progress in order of increasing atomic radius: Germanium (Ge) > Selenium (Se) > Bromine (Br) > Arsenic (As).

The element in group 1 with the smallest atomic radius is lithium, due to its higher nuclear charge compared to the other elements in the group (such as sodium and potassium). This higher nuclear charge attracts the electrons more strongly, leading to a smaller atomic radius.
