All the remaining ones have half-lives ranging from 30 minutes to less than a millisecond. [16] The neutron capture product of fermium-257, 258 Fm, undergoes spontaneous fission with a half-life of just 370(14) microseconds; 259 Fm and 260 Fm also undergo spontaneous fission (t 1/2 = 1.5(3) s and 4 ms respectively).

When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero.

Francium is a chemical element; it has symbol Fr and atomic number 87. It is extremely radioactive; its most stable isotope, francium-223 (originally called actinium K after the natural decay chain in which it appears), has a half-life of only 22 minutes.
Using the Federal Reserve’s $2.3 trillion M0 currency figure and a current world population of 8.17 billion, per Worldometer, there’s about $282 per person in the world, on average. Using the ...
Suppose multiple fermions have the same spatial probability distribution, then, at least one property of each fermion, such as its spin, must be different. Fermions are usually associated with matter, whereas bosons are generally force carrier particles. However, in the current state of particle physics, the distinction between the two concepts ...
