In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.
An element with an atomic number that is 20 greater will be bigger because when an element is bigger, it will have more particles (electrons, protons, and neutrons) which means that the atom will get bigger which will cause it to have a bigger radius.
