Lanthanides - Properties of Element Groups

The lanthanides are a group of 15 chemical elements, with atomic numbers 57 through 71. All of these elements have one valence electron in the 5d shell. The elements share properties in common with the first element in the group -- lanthanum. The lanthanides are reactive, silver-colored metals.

Lanthanide - Wikipedia

  

2019-8-15  The informal chemical symbol Ln is used in general discussions of lanthanide chemistry to refer to any lanthanide. All but one of the lanthanides are f-block elements, corresponding to the filling of the 4f electron shell; depending on the source, either lanthanum or lutetium is considered a d-block element, but is included due to its chemical ...

Lanthanides: Properties and Reactions - Chemistry

Lanthanides exhibit strong electromagnetic and light properties because of the presence of unpaired electrons in the f-orbitals. 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.

Actinides (Actinide Series) Element Properties

The actinides successively fill the 5f sublevel. Many actinide metals have properties of both d block and f block elements. Actinides display several valence states (typically more than the lanthanides). Most are prone to hybridization.

Lanthanide Series Encyclopedia

2019-8-18  The lanthanides form alloys with many other metals, and these alloys exhibit a wide range of physical properties. The lanthanides react slowly with cold water (more rapidly with hot water) to form hydrogen gas, and readily burn in air to form oxides. Oxides are substances in which a metal and oxygen have chemically combined to form a compound.

Lanthanides - Properties Of The Lanthanides -

Lanthanides Properties Of The Lanthanides. Like many metals, the lanthanides have a bright silvery appearance. Five of the elements (La, Ce, Pr, Nd, Eu) are very reactive and when exposed to air react with oxygen to form an oxide coating that tarnishes the surface. For this reason these metals are stored under mineral oil.

These elements are characterized by the filling up of the antepenultimate 4f energy levels. They are extremely similar to each other in properties, and until 1907 they were thought to be a single element. In the past, they were called the rare earths. This name is not appropriate because many of the elements are not particularly rare. Furthermore, the name is not precise since in addition to the 14 lanthanides it has been u...

They are available in ‘monazite’ sand’ as lanthanide orthophosphates.

Lanthanides and Actinides Introduction to Chemistry

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.

Lanthanide contraction - Wikipedia

2019-8-4  The lanthanide contraction is the greater-than-expected decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, which results in smaller than otherwise expected ionic radii for the subsequent elements starting with 72, hafnium. The term was coined by the Norwegian geochemist Victor Goldschmidt in his series "Geochemische ...
