That's impossible. The Atomic Mass is the number of protons plus the number of neutrons.
If you meant the element with atomic number 61, the name is Promethium. But it doesn't have 108 neutrons.

What is the only synthetic element in the lanthanide series?
Promethium, Pm, atomic number 61
What is the name of the element with the lowest atomic number?
Technetium - its atomic number is 43.
Pm is the chemical symbol for what?
Promethium is a chemical element with the symbol Pm and atomic number 61
The number of iron atoms in 61 g of iron?
The atomic mass of iron is 55.845, and the number of atoms in one gram-atomic mass is the Avogadro Number 6.02 X 1023. Therefore the answer to this question is (61/55.845) X 6.02 X 1023 = 6.6 X 1023. (Only two significant digits are justified by the significance-limiting datum 61.)
What element continue to decay until they finally become stable?
All elements above the atomic number of 83 are radioactive, but two elements that are under it are also radioactive. They are technetium (atomic number 43) and promethium (atomic number 61). Radioactive elements are elements that decay until stable. =)
What is atomic number 61?
