It was the first time that the Enrico Fermi Prize had been awarded to non-Americans, and the first time it was presented to a woman. [146] Meitner's diploma bore the words: "For pioneering research in the naturally occurring radioactivities and extensive experimental studies leading to the discovery of fission". [147]
If two elements can form three compounds between them, then the third compound is a "quaternary" compound containing one atom of the first element and three of the second. [20] Dalton thought that water was a "binary compound", i.e. one hydrogen atom and one oxygen atom.
Regardless of who was first to split the atom, the work of Rutherford, Walton, Cockcroft, Oppenheimer, Fermi, Geiger, Marsden and a host of other scientific pioneers paved the way for the nuclear ...
Fission is a form of nuclear transmutation because the resulting fragments (or daughter atoms) are not the same element as the original parent atom. The two (or more) nuclei produced are most often of comparable but slightly different sizes, typically with a mass ratio of products of about 3 to 2, for common fissile isotopes .

Nuclear binding energy, the energy required to split a nucleus of an atom. Nuclear potential energy , the potential energy of the particles inside an atomic nucleus. Nuclear reaction , a process in which nuclei or nuclear particles interact, resulting in products different from the initial ones; see also nuclear fission and nuclear fusion .
The kilonova briefly mimicked the conditions immediately following the Big Bang, and allowed scientists to confirm the source of the heavy elements Strontium and Yttrium for the very first time.
In it, Asimov presents the atom and subatomic particles in a historical context, beginning with Democritus's original thought experiments and theory of atomism, and ending with then-current knowledge of the fundamental particles. [1]
