lanthanides
Lanthanides are considered to be relatively soft metals. They are known to be malleable and ductile, meaning they can be easily shaped and stretched without breaking.
Elements with atomic numbers of 58 through 71 are known as the lanthanides, a group of transition metals that have similar properties and are often found together in nature. They are commonly used in various applications such as magnets, catalysts, and electronic devices.
lanthanides
Elements from atomic number 57 (Lanthanum) to 71 (Lutetium) are called the Lanthanides. Lanthanide means "like Lanthanum" and so, the Lanthanides are based on Lanthanum. Only one of the Lanthanides is radioactive: Promethium (Pm - No. 61)
Actinides comprise of atomic number 90-103. They are placed at bottom of periodic table.
Wht is the difference between Lanthanides and Actinides?
The two periods below the periodic table are known as the lanthanides and actinides. These series consist of elements that fall within the f-block of the periodic table.
