What is the group number for Lanthanides and Actinides?
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.
What are the elements of 4F series called?
The elements of the 4f series are called lanthanides. They are a group of metallic elements that have similar properties and occupy the f-block of the periodic table.
What is the state of matter for lanthanides?
Lanthanides exist as solids at room temperature and pressure. They have metallic properties and are typically soft, malleable, and ductile.
Are lanthanides gases at room temperature?
No, lanthanides are not gases at room temperature. They are a group of metallic elements that are solid at room temperature.
Were are the lanthanides placed on the periodic table?
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.
What is the difference between lanthanides and actinides?
Wht is the difference between Lanthanides and Actinides?
What about the complex formation ability of lanthanides as campared to actinides?
describe the complex formation by lanthanides?
Are lanthanides radioactive?
Some lanthanides are radioactive, such as promethium. However, most lanthanides found in nature are stable.
Do actinides and lanthanides lose electrons when combining?
Actinides and lanthanides lose electrons and form cations.
What is the group number for Lanthanides and Actinides?
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.

Where are the lanthanides?
They are located in the f-block

Are lanthanides gases at room temperature?
No, lanthanides are not gases at room temperature. They are a group of metallic elements that are solid at room temperature.
How variable are the densities of the lanthanides of the lanthanides compared to the densities of the actinides?
The densities of the lanthanides generally have less variability compared to the densities of the actinides. This is because the lanthanides are more similar in size and electronic structure, leading to more consistent densities. In contrast, the actinides exhibit larger variations in density due to differences in atomic structure and electron configurations.
Where are lanthanides located on the periodic table?
In most wide form periodic tables, the lanthanides are in a row below the normal part of the table, with a reference showing that all the lanthanides correspond to period 6 column 3. Sometimes the lanthanide element with the lowest atomic number, lanthanum itself, is shown in the main table and the other lanthanides in a row below the main table.
The first period at the bottom is called?
lanthanides
