It is krypton as it the far most right on the Periodic Table, having the smallest radius
The element in period 4 with the smallest atomic radius is argon. It has a smaller atomic radius compared to the other elements in period 4 because it is a noble gas with a full valence shell, resulting in a small atomic size.
The smallest atomic radius in period 5 belongs to the element with the highest nuclear charge, which is iodine (I) from Group 17. This is because as you move across a period, the nuclear charge increases, leading to stronger attraction for the electrons and a smaller atomic radius.
The element with the smallest atomic radius among calcium, potassium, scandium, and titanium is titanium. Atomic radius generally decreases from left to right across a period in the periodic table, and titanium is located towards the right side of the group mentioned.
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.
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).
Fluorine
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
The element in period 4 with the smallest atomic radius is argon. It has a smaller atomic radius compared to the other elements in period 4 because it is a noble gas with a full valence shell, resulting in a small atomic size.

It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
The smallest atomic radius in period 5 belongs to the element with the highest nuclear charge, which is iodine (I) from Group 17. This is because as you move across a period, the nuclear charge increases, leading to stronger attraction for the electrons and a smaller atomic radius.
It is hydrogen.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius
The element with the smallest atomic radius among calcium, potassium, scandium, and titanium is titanium. Atomic radius generally decreases from left to right across a period in the periodic table, and titanium is located towards the right side of the group mentioned.
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.
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.
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.
