How is rutherfordium created?
Rutherfordium can be produced by the nuclear fusion of plutonium-242 with neon ions. It can also be obtained through bombardment of californium-249 with carbon ions.
Is rutherfordium man made?
On the periodic table of elements, rutherfordium is represented by the symbol Rf. It has an atomic number of 104 because it has 104 protons in its nucleus. It is a synthetic element because it is created in a laboratory rather than occurring naturally.
Is rutherfordium a non metal?
Rutherfordium is a chemical element with symbol Rf and atomic number 104. Classified as a transition metal, Rutherfordium is a solid at room temperature.
Is rutherfordium harmful to humans?
Toxicity: Rutherfordium is expected to be harmful to living organisms due to its radioactivity. It is not an essential nutrient for any known life. Uses: At present, element 104 has no practical uses and is only application to research.

How is rutherfordium made as a synthetic element?
Rutherfordium is a synthetic element. This means that it was made in a laboratory setting rather than found when mining. In order to make synthetic elements, scientists use a process called artificially induced radioactivity.
How is rutherfordium produced in a nuclear bomb?
Abundance and Isotopes. Source: Rutherfordium is a synthetic radioactive metal, created by nuclear bombardment, and has only been produced in tiny amounts. Rutherfordium can be made by bombarding plutonium-242 with accelerated neon ions or by bombarding californium-249 with accelerated carbon ions.
What are the physical characteristics of rutherfordium ( Rf )?
Physical Characteristics. Rutherfordium is solid under normal condition. It isa very heavy element and has a high density of about 23.2 g/cm 3. Its melting point is very high, about 2100 o C. Boiling point of rutherfordium is also very high, 5500 o C. Its chemical symbol is Rf and the atomic number is 104. Its atomic weight is 267 g/mol [2].
What are the names of the isotopes of rutherfordium?
As explained in the history of this element, rutherfordium has several isotopes or different forms of the element with different numbers of neutrons. When discovered, Russia was able to make Rf-259, while scientists from Berkeley, California were able to make the isotopes Rf-257, Rf-258, and Rf-260.
