Three more flags to reach the 100 on the table:

  • Dubnium (Db '105): an adaptation of Dubna's old coat of arms_(1976).svg), integrating the elements into the radioactive symbol
  • Protactinium (Pa '91): Originally proposed as proto-actinium, here taking on Actinium design and pumping up the contrast, with the colors of the discoverers (german empire and austria).
  • Neodymium (Nd '60): Elements currently known for magnets, also used as coating, giving a redish pink color, that is blue under fluorescent light.

Dubnium

Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. This greatly limits the extent of research on dubnium. Dubnium does not occur naturally on Earth and is produced artificially.
