In the first decay, element 115 turned into element 113 while emitting a chunk known as an alpha particle.
During the summer of 1940, Edwin McMillan and Philip Abelson of the University of California, Berkeley, discovered element 93 (naming it neptunium, after the next planet after Uranus, for which uranium was named); they inferred that this element would decay into element 94.

The first, electromagnetism, involves the everyday forces applied by electric and magnetic fields, and the second, called the weak force, causes the radioactive decay of elements like radium and uranium.
During solar system formation, as asteroids accreted, the heat generated from the radioactive decay of elements (such as 26Al and 40K) was trapped in the interiors of these bodies, which began to warm up.
Radioactive decay of elements within Mercury's crust is another source of helium, as well as sodium and potassium.
We propose that the scarcity of old copies in the anole genome results from the rapid decay of elements, caused by a high rate of DNA loss.
6 7 Notable among these is radon, a naturally occurring inert gas formed from the radioactive decay of elements of the uranium series, which seeps into homes through the floor, especially in areas with predisposing geology and soil type.
Scientists describe helium as a nonrenewable gas, lighter than air and often found in natural gas fields after being formed by decaying radioactive elements.
To identify putative or decaying IS elements, a PSI-TBLASTN search was performed on all three genomes, identifying 36%, 39%and12%2% additional putative transposase ORFs than originally annotated in strains CcI3, EAN and ACN, respectively.
