Although bismuth-209 is now known to be unstable, it has classically been considered to be a stable isotope because it has a half-life of over 1.9Ã10 19 years, which is more than a billion (1000 million) times the age of the universe.ismuth (Bi) has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic mass can be given as 208.9803987(16) u.
Following through on his State of the Union pledge, President Barack Obama has signed an Executive Order raising the minimum wage for workers on new federal contracts to $10.10 per hour. The rate increase will apply only to solicitations and contracts issued on or after January 1, 2015.
