Unveiling Rutherfordium: A Synthetic Element’s Discovery and Properties

Rutherfordium: The Synthetic Transition Metal You Need to Know

As we delve deeper into the world of chemistry and nuclear physics, we come across a vast array of elements that make up the periodic table. One such element that we’ll be discussing here is rutherfordium.

Rutherfordium is an artificially created radioactive transition metal with the atomic number 104. Let’s go through this article to gain a better understanding of this synthetic element.

Discovery and Naming of Rutherfordium

Georgy Flerov and his colleagues discovered rutherfordium in 1964 by bombarding plutonium-242 with neon ions in a cyclotron. The researchers observed the decay chains of the resultant nuclei, including rutherfordium.

Later, Albert Ghiorso and his team, in a joint effort with Flerov, managed to produce the element using a new method, bombarding a Californium-249 target with carbon-12 ions, in 1969. Finally, the International Union of Pure and Applied Chemistry (IUPAC) officially recognized rutherfordium as an element in 1997.

The element was named for New Zealand-born physicist Ernest Rutherford, who, along with being the father of nuclear physics, also discovered the concept of radioactive decay. Rutherford played a pivotal role in the discovery of sub-atomic particles like the proton and neutron.

Identification of Rutherfordium

Rutherfordium has the atomic symbol Rf and an atomic number of 104. It has the highest atomic number of all elements that have been discovered so far.

The element’s CAS number is 53850-36-5, and it falls in group 4 of the periodic table, under titanium, zirconium, and hafnium. Rutherfordium has no stable isotopes and has a range of isotopes with half-lives ranging from seconds to hours.

Properties and Characteristics of Rutherfordium

Due to its synthetic nature, only very small amounts of rutherfordium have ever been produced, which makes analyzing its properties challenging. However, researchers have been able to deduce some of its chemical and physical properties from experimental results.

The element has an atomic mass of roughly 267 atomic mass units and a melting point of around 2100C. Rutherfordium at room temperature is expected to be a solid or liquid with a silvery-white metallic luster, highly ductile and malleable metal.

It is predicted to be chemically similar to its neighbouring element, hafnium. Rutherfordium is highly unstable and radioactive.

Its most stable isotope, Rf-267, has a half-life of around 1.3 minutes.

Uses and Danger of Rutherfordium

Since rutherfordium is an artificially created element, it has no practical applications. Researchers use rutherfordium only for scientific purposes, especially to advance our understanding of nuclear physics.

Due to its highly radioactive nature, it poses a significant health hazard and requires careful handling by qualified experts in a securely guarded laboratory setting. If ingested, inhaled, or otherwise taken into the body, radiation poisoning can occur, leading to severe organ damage or death.

Name Origin of Rutherfordium

We now know that the element rutherfordium was named after the Father of Nuclear Physics, Ernest Rutherford. Rutherford played a huge role in various scientific breakthroughs, discovering sub-atomic particles and contributing to our knowledge of the nucleus of atoms.

Through his experiments, he established that atomic nuclei contained positively charged particles, later called protons, and showed that atomic nuclei had a dense center he called the nucleus.


Rutherfordium has proven to be an essential element in the field of nuclear physics. From its discovery to its properties, we can see the significance of this element.

We learned that it was discovered in a cyclotron, has a short half-life, and is incredibly unstable and radioactive. We hope that this article has provided a comprehensive yet concise overview of this synthetic transition metal.

Please take note that since the element is highly dangerous, it should only be handled by qualified professionals in a carefully guarded laboratory environment.

Discovery of Rutherfordium

The discovery of rutherfordium is a testament to the human quest to uncover new elements and expand our understanding of the world around us. Rutherfordium, with its atomic number 104, was first discovered in Dubna, Russia, and later in Berkeley, California, by two different teams of researchers.

Flerov’s Discovery

The first discovery of rutherfordium was made in Dubna, Russia by a team led by Georgy Flerov. In 1964, Flerov and his colleagues bombarded a sample of plutonium-242 with neon ions in a cyclotron.

The researchers observed the decay chains of the resultant nuclei, including rutherfordium. Flerov’s team continued to study the results, eventually identifying the decay chain of the element they were looking for.

However, it wasn’t until five years later when they published their findings, including the discovery of element 104, that the entire scientific community became aware of its existence. Ghiorso’s Discovery

The second discovery of rutherfordium was made by a team led by Albert Ghiorso at the Lawrence Berkeley National Laboratory.

In 1969, they produced a small quantity of the new element by bombarding a curium-248 target with an oxygen-18 nucleus. The reaction produced the new element, as well as four neutrons.

The researchers used a system of chemical separations and ion exchange to isolate the new element from the rest of the reaction products. They were able to identify the decay chain and confirm the existence of the new element.

The team named the new element rutherfordium in honor of the pioneering nuclear physicist, Ernest Rutherford.

Rutherfordium Identification

Identifying rutherfordium is a crucial part of understanding the element’s properties and potential applications. Scientists have used a variety of experimental techniques to identify the various physical and chemical properties of the element, providing valuable insights into its behavior.

Atomic Data

Rutherfordium has an atomic number of 104, which means that it has 104 protons in its nucleus. The number of protons defines the element’s identity, and it is the periodic table’s basis.

An atom of rutherfordium typically has a valence electron configuration of 6d2 7s2. This electron configuration is the basis for the element’s chemical properties, including its reactivity and its ability to form chemical bonds.

The energy levels, radius of the atom, and electronegativity of rutherfordium are difficult to calculate because of its rarity and associated instability. However, researchers have been able to use computational models and experimental data to estimate these values.

Rutherfordium Uses

Rutherfordium has no known practical uses outside of scientific research. It is challenging to produce and highly unstable, making it unsuitable for most practical applications.

Scientists use rutherfordium in nuclear physics research applications. Scientists use it to explore the properties of other elements and study the basic principles of nuclear physics and atomic structure.
