2 Interesting Facts about Actinoids

Welcome to the final part – part 8 in the Chemical Element Facts Series! Discover interesting facts about Actinoids in the periodic table and embark on a chemical journey!

89. Facts – Actinium

actinium facts
  • Isotope 227Ac occurs naturally through the decay of uranium minerals. Actinium metal can been prepared by reducing actinium fluoride with lithium vapor at about 1,100 to 1,300 degrees C (2,012 to 2,372 F).
  • Actinium’s high activity level makes it valuable in producing neutrons. There has been some work done to use 225Ac in treating cancer patients.

90. Facts – Thorium

Thorium facts
  • Berzelius isolated thorium by first mixing thorium oxide found in the mineral with carbon to create thorium chloride, which was then reacted with potassium to yield thorium and potassium chloride, according to Chemicool.
  • In its liquid state, thorium has a greater temperature range than any other element, with nearly 5,500 degrees Fahrenheit (3,000 degrees Celsius) between melting and boiling points.

91. Facts – Protactinium

Protactinium facts
  • One of the rarest naturally occurring elements, protactinium occurs in Earth’s crust in average concentrations of a few parts per trillion. This rarity makes it one of the most expensive natural elements.
  • Protactinium has 29 radioisotopes. Almost all naturally occurring protactinium is 231Pa. It has a half-life of 32,700 years and is an alpha emitter formed by the decay of 235U. Other uranium decays produce isotopes of protactinium. Nearly all uranium-238 (99.8 percent) decays first to the 234mPa isomer and then to 234Pa.

92. Facts – Uranium

uranium facts
  • The “Little Boy” bomb detonated 1,670 feet (509 meters) above Hiroshima and left only the frames of a few reinforced concrete buildings standing in the mile radius around Ground Zero, according to a 1980 Defense Nuclear Agency report. Firestorms destroyed everything within a 4.4-mile radius (7 kilometers) of the blast.
  • Marie Curie, who worked with uranium to discover several even more radioactive elements (polonium and radium), likely succumbed to the radiation exposure involved in her work. She died in 1934 of aplastic anemia, a red blood cell deficiency probably caused by radiation damage to her bone marrow.

93. Facts – Neptunium

neptunium facts
  • Neptunium’s current applications are limited. Neptunium has only been considered, not actually used, as a fissile nuclear fuel. However, neptunium-237 is used to create plutonium-238, which is then used in special energy generators that can power satellites, spacecraft and lighthouses for a long period of time. Neptunium-237 is also used in nuclear physics research as a part of a device that detects high-energy neutrons.
  • Although neptunium makes up only a small percentage of total radioactive waste, it poses a particular threat because it is long-lasting and hard to extract. Amy Hixon, an assistant professor at the Notre Dame College of Engineering, has studied the less familiar actinide elements and how to best contain them. 

94. Facts – Plutonium

plutonium facts
  • Plutonium is not magnetic. Other members of the element group stick to magnets, but plutonium can have a variable number of electrons in its valence shell, which makes it difficult for the unpaired electrons to align in a magnetic field.
  • Ordinarily, there are six allotropes, or forms, of plutonium. A seventh allotrope exists at high temperatures. These allotropes have different crystal structures and densities. Changes in environmental conditions readily cause plutonium to shift from one allotrope to another, making plutonium a difficult metal to machine. Alloying the element with other metals (e.g., aluminum, cerium, gallium) helps make it possible to work and weld the material.

95. Facts – Americium

americium facts
  • According to 1986 article published in Radiochemistry and Nuclear Chemistry by Norman Edelstein and Lester Morss, American researchers, americium is one of 15 actinide metals. Actinide elements range from atomic numbers 89 (actinium) through 103 (lawrencium). These elements are all radioactive with an unusual range of physical properties.
  • According to the World Nuclear Association, smoke detectors that use americium are popular in homes and are sensitive to the presence of smoke or heat. These smoke detectors are relatively inexpensive and are sensitive to a wide range of fire conditions. The isotope americium-241 is used in these detectors as americium dioxide (AmO2).

96. Facts – Curium

curium facts
  • Currently, curium is used primarily for basic scientific research. Some of its isotopes, however, have proven uses. 242Cm generates about three watts of thermal energy per gram, more than plutonium produces. Both 242Cm and 244Cm have been used as power sources for space and medical practices.
  • Curium has 14 known isotopes. They range in mass from 237 to 251. Though none are stable, 247Cm has a half-life of about 15,600,000 years. It decays into 243Pu through alpha decay.

97. Facts – Berkelium

berkelium facts
  • Berkelium was first produced at the University of California, Berkeley, in 1949 by Stanley G. Thompson, Glenn T. Seaborg, Kenneth Street Jr. and Albert Ghiorso. Initial investigations were limited to tracer experiments (ion exchange and co-precipitation) but in 1952 experiments were initiated to provide macro amounts of berkelium.
  • Because it is artificially produced and only small amounts exist, berkelium’s primary use is in basic scientific research. It has proven quite useful in that regard.

98. Facts – Californium

californium facts
  • In 1950, American scientists Stanley Thompson, Kenneth Street, Albert Ghiorso and Glenn Seaborg first produced californium in a lab at the University of California, Berkeley. It was the sixth synthetic transuranium (“beyond” uranium) element in the actinide group to be discovered. The discovery occurred when the chemists bombarded curium-242 with alpha particles (helium atoms without electrons) in a 60-inch cyclotron particle accelerator.
  • Each nuclear reaction created Cf-245 — an isotope with a half-life of about 45 minutes — and a free neutron. The scientists produced around 700,000 atoms of Cf-245, just enough to make a cube with sides measuring only 27 nanometers, according to Chemicool. After a chemical analysis, the scientists confirmed that a new element had been discovered. 

99. Facts – Einsteinium

einsteinium facts
  • Einsteinium, the 99th element on the Periodic Table of Elements, is a synthetic element that is produced in extremely small amounts and with a very short lifetime. If the name seems familiar, it’s because it is indeed named after famed physicist Albert Einstein, although he had nothing to do with the element’s discovery or research.
  • Scientists at Lawrence Berkeley National Laboratory, the Argonne National Laboratory, and the Los Alamos Scientific Laboratory published the discovery of einsteinium and fermium on June 9, 1955, for the United States Atomic Energy Commission.

100. Facts – Fermium

fermium facts
  • Fermium’s chemical properties have been studied only with tracer amounts requiring innovative experimental techniques. It has been discovered that fermium’s chemistry is typical of late actinides, with a III oxidation state prevailing but also a tendency toward a II oxidation state present.
  • Since fermium is found only in small quantities and all its isotopes have short half-lives, there is no commercial use for the element. It is, however, used in scientific research that expands the knowledge of the rest of the periodic table.

101. Facts – Mendelevium

mendelevium facts
  • In early 1955, Stanley Thompson, Glenn Seaborg, Bernard Harvey, Gregory Choppin and Albert Ghiorso at the University of California, Berkeley, bombarded Einsteinium-53 with helium ions in the Berkeley 60-inch cyclotron. It produced a new isotope, 256Md, which was notable for revealing the existence of mendelevium and also for being the first isotope synthesized on a one-atom-at-a-time basis.
  • Only small quantities of mendelevium have ever been produced, so it has no commercial uses. It is used only for scientific research. The isotope 256Md has been helpful in understanding some of the chemical properties of mendelevium in aqueous solution.

102. Facts – Nobelium

nobelium facts
  • Nobelium is a member of the actinide series and little is known about it. There are 10 recognized isotopes of nobelium. The most stable is 259No, which has a half-life of about 58 minutes. 
  • Nobelium is artificially produced, and it has never been made in great quantities. It can be produced by bombarding Curium-246 with Carbon-12 ions.

103. Facts – Lawrencium

lawrencium facts
  • It can be produced by bombarding californium placed in a linear accelerator with boron ions. This method has been used in multiple experiments and several different isotopes of lawrencium have been produced this way.
  • Because lawrencium has only been produced in small quantities, its only use is for scientific research.
