Rutherfordium is a synthetic chemical element; it has symbol Rf and atomic number 104. It is named after physicist Ernest Rutherford. As a synthetic element, it is not found in nature and can only be made in a particle accelerator. It is radioactive; the most stable known isotope, 267 Rf, has a half-life of about 48 minutes.
rutherfordium (Rf), an artificially produced radioactive transuranium element in Group IVb of the periodic table, atomic number 104.
30 Μαΐ 2019 · Sources of Element 104: Element 104 has not been found in nature. It is only produced by nuclear bombardment or decay of heavier isotopes. In 1964, researchers at the Russian's facility at Dubna bombarded a plutonium-242 target with neon-22 ions to produce the isotope most likely rutherfordium-259.
- The element is not found naturally; it must be synthesized in a laboratory. - It has no stable isotopes, making its abundance in the Earth's crust or universe effectively zero. - It is typically produced by high-energy particle accelerators.
30 Δεκ 2019 · Rutherfordium (Rf) is a radioactive metal that has the atomic number 104 in the periodic table, its appearance is not fully known due to the minuscule amounts produced of it. It is a Transition metal in Group 4. It has the symbol Rf.
24 Μαΐ 2019 · Rutherfordium is a synthetic chemical element. Its official chemical symbol is Rf, and its atomic number is 104, which means that a rutherfordium atom has 104 protons in its nucleus. Rutherfordium was the first super-heavy element to be discovered.
