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.

What is the element in period 4 with the smallest atomic 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.


Which of the following has the smallest atomic radius P AL S Si Cl?

Atomic radius increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl


Period 4 element with smallest atomic radius?

The period 4 element with the smallest atomic radius is chlorine, which has a greater number of protons in the nucleus pulling the electrons closer, making it smaller compared to other elements in the same period.


Which element has the large atomic radius?

Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
