Today natural elements are considered the elements up to the atomic number 98; but the elements with atomic numbers 43, 61 and 93-98 exist only in extremely traces, as a curiosity in uranium deposits. Of course they can be obtained also by man made nuclear reactions.
Consequently man made elements must be considered only the elements with the atomic number over 98: some examples are meitnerium, bohrium, flerovium.
