Lanthanides - Properties of Element Groups

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.

Lanthanide - Simple English Wikipedia, the free encyclopedia

A lanthanide is one of a group of 15 elements that have atomic numbers 57 to 71. This is also known as the lanthanide series or lanthanoid series.This group starts at lanthanum and it ends at lutetium. All lanthanoids are f-block elements, meaning that electrons fill the 4f electron shell, except for lutetium which is a d-block lanthanoid. The lanthanoid series (Ln) is named after lanthanum.

Why do lanthanides have remarkable similar properties? - Quora

Answer (1 of 3): Thank you for question. The simplest explanation is that the 4f sub-shell of the lanthanoids is an inner-inner sub-shell. So, in chemical reactions, the 4f electrons are usually buried too deeply to be involved in chemistry. What does that leave? Most of the Ln have an outer el...

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.
