This document lists the atomic number, symbol, element name, number of protons, number of electron shells, and number of electrons in each shell for various elements in the periodic table. It provides this information for elements from hydrogen to radon, covering the first seven periods of the periodic table. The elements are grouped according to their chemical family. For each element, the atomic number increases from left to right within each family as the number of protons and electrons increases in a predictable fashion based on the element's position in the periodic table.
