How new elements are synthesized
Plutonium (Pu, atomic number 94), first synthesized in 1940, is another such element. It is the element with the largest number of protons (atomic number) to occur in nature, but it does so in such tiny quantities that it is far more practical to synthesize it. Plutonium is known mainly for its use in atomic bombs and … Se mer A synthetic element is one of 24 known chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, … Se mer All elements with atomic number greater than 94 decay quickly enough into lighter elements such that any atoms of these that may have existed when the Earth formed (about 4.6 billion years ago) have long since decayed.

Elements with atomic numbers greater than 92 (atomic number of uranium) are called transuranium elements They were discovered in the laboratory using nuclear reactors or particle accelerators. Dmitri Mendeleev created a classification of elements based on their atomic weight.
