Uses of Lanthanides. The Actinides have a radioactive nature. study Specifically, elements in this family range in atomic mass from 227g/mol to 262g/mol. Sciences, Culinary Arts and Personal Well if you look at the periodic table on screen now, you will see a dark pink row at the very bottom. The symbol An is used while referring to any of the actinide series elements which range in the periodic table from atomic numbers 89 to 103. Actinide definition is - any of the series of elements with increasing atomic numbers that begins with actinium or thorium and ends with lawrencium. Thorium is used majorly in Gas mantles. They were fascinating topics of research for scientists but of little practical interest. Likewise several of the naturally occurring actinides are used in areas ranging from medical imaging to powering spacecraft. The lanthanides and actinides together are sometimes called the inner transition elements. Therefore, curium and plutonium are used as power sources on the Moon to provide electrical energy for transmitting messages to Earth. You can test out of the History of the Actinides All rights reserved. The first few elements in the lanthanide series are very reactive (La to Pm). {{courseNav.course.mDynamicIntFields.lessonCount}} lessons U-235 is fissionable, it is used as fuel in nuclear power plants and as a component in nuclear weapons. As mentioned earlier, elements in the actinide family are heavy due to their large atomic mass. Uses Of Actinides. © copyright 2003-2020 Study.com.

Their reactivity makes them ideal for specialist applications in various industries. {{courseNav.course.topics.length}} chapters | Mg- alloys containing 30% mishmetal and 1% Zr are useful in making parts of jet engines. The removal of the most long-lived radiotoxic elements from used nuclear fuel, minor actinides, is foreseen as an essential step toward increasing the public acceptance of nuclear energy as a key component of a low-carbon energy future. A reduction in atomic and ionic radii from Actinium to Lawrencium is seen. Explore this lesson to learn about what the actinides are, their properties, and uses. Can you spot an actinide on a periodic table? Thorium has been used since the late 19th century in the production of gas mantles.
