Man-made elements, also known as synthetic elements, are primarily found in the actinide and transactinide series of the Periodic Table, specifically in periods 7 and 8. Examples include elements like plutonium (Pu, atomic number 94) in the actinides and elements beyond uranium, such as seaborgium (Sg, atomic number 106) and oganesson (Og, atomic number 118) in the transactinides. These elements are typically created in laboratories or nuclear reactors and are often highly unstable with short half-lives.
