Elements 58 to 71 are called the Lanthanides.
Elements between 57 and 70 belongs to the f group. Elements from La - Lu belongs to this group. These are called Lanthanides.These elements are Lanthanides. They are placed separately. They have different chemical properties.
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)
The elements beginning with Lanthanum (atomic number 57) and ending with Lutetium (atomic number 71) are called Lanthanides. They are also known as rare earth elements.
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)
Lanthanoids are placed down in the periodic table.They contain elements with atomic number 57 to 71.There are total 15 elements in lanthanoids group.
Elements between 57 and 70 belongs to the f group. Elements from La - Lu belongs to this group. These are called Lanthanides.These elements are Lanthanides. They are placed separately. They have different chemical properties.
elements 57 - 70.
Elements 57 through 70 on the Periodic Table are part of the Lanthanide Series
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)
they are not placed from elements 57-70.
These elements are the lanthanides; see the link below for some details.
Lanthanides
between Barium and Hafnium
70 - 57 = 13
The are the lanthanoids and actinoids elements.
The elements with atomic numbers between 57 and 71 are called lanthanoids (or lanthanides).
70% of 57 is 39.9.
