The atomic mass of neptunium is approximately 237 grams per mole. Since 1 mole of any element contains Avogadro's number of atoms (approximately 6.022 x 10^23 atoms), one atom of neptunium would weigh approximately 237 grams divided by Avogadro's number, which is a very tiny fraction of a gram.
Neptunium trifluoride is an intermediate for the preparation of neptunium metal.
