Lanthanum and actinoids have different properties. So they are placed seperately.
Lanthanum and actinium have different properties. So, they are kept apart from the periodic table.
Lanthanum and Actinium
Lanthanum is a metal. It is a transition metal that belongs to the lanthanide series in the periodic table.
Lanthanum is located on the right to the bottom side on the periodic table.
The element Lanthanum (La) is a transition metal and the first of the 'Lanthanides'.
The atomic number of the element lanthanum on the periodic table is 57.
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 termed as lanthanide because the lighter elements in series are chemically similar to lanthanum
The lanthanides are a series of elements that are placed at the bottom of the periodic table. They are located in the f-block, specifically in the period below the main body of the periodic table. The lanthanides have atomic numbers 57-71.
After the new IUPAC nomenclature: yes.
