FAQ
Frequently Asked Questions
Yes, all known transuranic elements are radioactive and have no stable isotopes.
Minute traces of some, like neptunium and plutonium, can form naturally in uranium ore from neutron capture, but they are primarily human-made in laboratories.
Neptunium (atomic number 93) is the first element in the transuranic series.
They are crucial in nuclear reactors, nuclear weapons, and scientific research for understanding the limits of the periodic table and nuclear structure.
A chemical element with an atomic number greater than that of uranium (92), which is the heaviest naturally occurring element on Earth.
Transuranic element is usually scientific, technical in register.
