Chemical Elements - JSON
Chemical elements are the fundamental units of matter defined by the number of protons in their atomic nucleus (atomic number). Currently, 118 elements have been confirmed and organized in the periodic table. Elements are classified into metals, nonmetals, metalloids, and noble gases, each possessing unique physical and chemical properties. In 2016, element 118, Oganesson, was officially named, completing the 7th period of the periodic table.
