2. maN-Made elements Man-made elements or Synthetic elements are unstable chemical elements and they are not naturally found on the earth. These elements are synthesized in the laboratory. All of them are unstable and radioactive in nature, which means they emit radiations and decay into other elements. Their discovery helped to fill the empty gaps in the periodic table, and they were later produced for research purposes.
