what group is the lanthanide and actinide series?
220268
The lanthanides and actinides form a group that appears almost disconnected from the rest of the periodic table. This is the f block of elements, known as the inner transition series. This is due to the proper numerical position between Groups 2 and 3 of the transition metals.
529347
The lanthanide and actinide series make up the inner transition metals. The lanthanide series includes elements 58 to 71, which fill their 4f sublevel progressively. ... Actinides are typical metals and have properties of both the d-block and the f-block elements, but they are also radioactive.

lanthanide series, a series of metallic elements, included in the rare-earth metals , in Group 3 of the periodic table . Members of the series are often called lanthanides, although lanthanum (atomic number 57) is not always considered a member of the series.

The reason why Lanthanides and Actinides are located at the bottom of the periodical table is because of their properties and in the block in which electrons fill up. ... The reason why inner-transition metals are located at the bottom of the periodic table, separated from the rest is because they all fill the f-block.

They are called the lanthanides because they exhibit similar chemical properties to lanthanum, the first element in the group. Actinides are the 15 elements with atomic numbers from 89 to 103. They are named after the first element in the series, actinium.

The elements cerium (Ce, atomic no. 58) through lutetium (Lu, atomic no. 71) are commonly known as the lanthanide series.

Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission. The three most relevant fissile isotopes are uranium-233, uranium-235 and plutonium-239.

An inner transition metal (ITM) of chemical elements on the periodic table. They are normally shown in two rows below all the other elements. They include elements 57-71, or lanthanides, and 89-103, or actinides. The lanthanides are very similar, and the actinides are all radioactive.

Actinides are the 15 elements with atomic numbers from 89 to 103. They are named after the first element in the series, actinium. The actinides group includes mostly man-made elements with only a few exceptions such as uranium and thorium.
1392083
Elements Lanthanum (57) through Lutetium (71) on the periodic table are considered to be Lanthanides. ... The majority of the Lanthanides are paramagnetic, which means that they have strong magnetic fields. Both the Lanthanides and Noble Gases tend to bind with more electronegative atoms, such as Oxygen or Fluorine.

Question: Anomalous Electron Configurations Some Atoms, Such As Some Transition Metals And Some Elements In The Lanthanide And Actinide Series, Do Not Adhere Strictly To Hund's Rule And Pauli's Principle. The Reason The Anomalies Are Observed Is The Unusual Stability Of Both Half-filled Pnd Completely Filled Subshells.

Both lanthanides and actinides are radioactive. Radioactivity is an important property, especially when it comes to nuclear power. ... Also, their radioactive properties allow these elements to release energy in the form of rays. This property is useful in certain medical applications, such as x-rays.

The actinides are elements 89 to 103 and fill their 5f sublevel progressively. Actinides are typical metals and have properties of both the d-block and the f-block elements, but they are also radioactive.

The elements scandium and yttrium are also known as the “rare earths” because they were originally discovered together with the lanthanides in rare minerals and isolated as oxides, or “earths.” Collectively, these metals are also called rare earth elements (REEs).
631068
Rare Earth metals are a set of 17 chemical elements in the periodic table, specifically the fifteen lanthanoids plus scandium and yttrium. All lanthanoids are relatively soft and reactive metals. The rare earths metals are silver, silvery-white or gray metals which have a high luster, but tarnish readily in air.
