many. one example is lead-214 with a halflife of 26.8 minutes.
Illadelph Halflife was created on 1996-09-24.
Yes.
A sample of 187 rhenium decays to 187-omium with halflife of 41.6 billion years. If all 188 osmium are normalized isotopes.
The logo has a border, however the lambda is in the center.
Yes, but it has a halflife of only 0.86 seconds.
Go out and buy it. You can't download it.
One generation is 25 years.
The half life of plutonium-235 is 25,3(5) minutes.
ALL elements have isotopes (even if its only one).Assuming you meant vanadium, it has one stable isotope: vanadium-51 (99.76%), but vanadium-50 (0.26%) is almost stable with a halflife of 100,000,000,000,000 years (almost 8000 times longer than the age of the universe). Vanadium also has many radioactive isotopes that must be created in nuclear reactors, nuclear explosions, particle accelerators, or stellar novas.
The half life of uranium is not one day. For an isotope with the half life or one day, after 3 days: the quantity remained is 12,5 %.
