lanthanide

Chemically, the lanthanide elements are all quite similar to each other.

Across the lanthanide series, electrons are added to the 4f shell.

It is a lanthanide oxide, also known as a rare earth.

Examples are elements found in the lanthanide and actinide series.

Part of the lanthanide series, holmium is a rare earth element.

It forms alloys with lanthanide metals but little is known about them.

It was in this book that he coined the term lanthanide contraction.

Similar effect is observed in monochalcogenides of another lanthanide, thulium.

It is produced mainly as a by-product of lanthanide and uranium production.

About 10% of the lanthanide contraction has been attributed to relativistic effects.

It is the last element in the lanthanide series, and traditionally counted among the rare earths.

This sometimes is believed to be the inclusion of all 30 lanthanide and actinide elements as included in group 3.

The Sparkle model (for lanthanide chemistry) is also available.

All elements in the lanthanide series form M ions.

Cerium is a silvery metal, belonging to the lanthanide group.

This behavior is known as the lanthanide contraction.

Thulium is the least abundant lanthanide on earth except for promethium.

All the lanthanide elements exhibit the oxidation state +3.

Without the lanthanide contraction, a chemical separation of lanthanides would be extremely difficult.

They are particularly useful for binding lanthanide ions, which typically have coordination numbers greater than 6.

Many of these features make lanthanide complexes effective catalysts.

The elements following the lanthanides in the periodic table are influenced by the lanthanide contraction.

The informal chemical symbol Ln is used in general discussions of lanthanide chemistry.

A similar behavior is observed for the lanthanide analogue of berkelium, terbium.

For example, its structure is very similar to that of lanthanide oxide sulfates and therefore may be used to help better describe them.
