An element can’t be broken down any further. They are considered to be the smallest part of matter. The atomic mass of an element is the mass or weight of an element or atom. Inside of the atom are the protons and neutrons. This is what is included in most of the mass of the element. The atomic radius of an element is the distance from the nucleus to the outer layer of the element. Protons and neutrons can be found in the nucleus.

The electrons are located surrounding the atom. So, the atomic radius would be measuring from the protons to the electrons. This distance is measured in picometres. In this situation, the atomic radius can be determined based on the mass of the other elements.

166 fits in the range of 141 - 171, since Yy has a mass between that of Xx and Zz.
