The lanthanides and actinides are groups of aspects in the routine table. They are the elements that room often provided below the key section the the regular table. There room thirty total facets in the lanthanides and actinides. They space often dubbed the "inner shift metals."LanthanidesThe lanthanides are the elements with atomic numbers indigenous 57 come 71. This 15 metals (along with scandium and yttrium) are often dubbed the rare earth elements. They space all silvery-white steels which room often uncovered in the exact same ores. Lock are dubbed the lanthanides due to the fact that they exhibit comparable chemical properties to lanthanum, the an initial element in the group.ActinidesActinides space the 15 aspects with atom numbers indigenous 89 come 103. Castle are called after the an initial element in the series, actinium. The actinides group includes mostly artificial elements with only a couple of exceptions such as uranium and also thorium. The actinides are most known for the aspects uranium and also plutonium i m sorry are supplied in nuclear reactors and nuclear bombs.Interesting Facts about Lanthanides and ActinidesThe lanthanides and actinides room located mainly in the "f-block" the the regular table. Lanthanides are supplied in products such together hybrid cars, superconductors, and permanent magnets.The actinide americium is provided in smoke detectors.Elements that have actually an atomic number greater than uranium (92) space often referred to as "transuranium." many of these elements are artificial under the conditions of nuclear reactors.The an initial actinides discovered were uranium and also thorium.The surname "actinium" originates from the Greek indigenous "aktis" which means beam or ray.Both actinides and also lanthanides are highly reactive with elements from the halogen group.All of the lanthanides have actually at the very least one stable isotope except for promethium.None the the actinides have a stable isotope. They room all radioactive.

You are watching: Why are lanthanides and actinides at the bottom of the periodic table
