Shenzhou People called the elemental periodic table "Heavenly Order Table," not without reason.
For the atomic number of the elements in the elemental periodic table was actually the order in which these elements appeared in the cosmos—the "Heavenly Order."
Hydrogen appeared first, even earlier than the stars. The first-generation stars—the very first stars that formed in the universe—created helium and a series of successive elements through fusion.
Nuclear fusion transformed light elements into heavy elements. According to the atomic numbers in the periodic table, later elements gradually appeared. The conditions for the formation of later elements became increasingly stringent. Metals like gold, lead, and uranium even required novae and supernovae to form.
