The lanthanide series comprises the fifteen metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. These fifteen elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements.
In the Group 3, Period 6 slot, After Barium and prior to Hafnium.

Where are the Valero oil refineries located?
United States, Canada, United Kingdom, and the Caribbean.
Where would a steam separator be located on a boiler?
In the steam drum, where steam exits and flows to the superheaters.
Where is nzs largest oil refinery?
Marsden Point Oil Refinery is a refinery located at Marsden Point, Whangarei, Northland, New Zealand. It is the only oil refinery in New Zealand, and is operated by Refining NZ.
What are seal pots?
Seal pots (sometime called condensate pots) are used to allow a liquid seal between the instrument and flowing gases such as steam. Their function is to keep the liquid level constant in the impulse tubes. For example, in boiler liquid level applications the high pressure (HP) side of a differential pressure transmitter is connected to the vapor space on top of the steam drum. Steam condenses in the chamber or seal pot and fills the impulse line with condensate. The seal pot is located to allow the condensate to drain back to the source thus keeping the liquid level constant.
Where are refineries located?
No. The last refinery was built in 1976 and there are no plans to build any new ones. Existing petroleum refineries are experiencing declining operating revenues and are actually reducing their capacity to around 80%. This is in part due to the economic downturn and in part a result of a continuing downward trend in the refining industry that began in 2005. Imports of refined products are increasing to fill the gap between domestic supply and demand, though even these have declined as overall consumption has dropped from 2005-2008. Hope that helps!
Where are the lanthanides located?
They are located in the f-block
Where are the lanthanides?
They are located in the f-block
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.
What are the two rows of elements located below the main body of the table called?
the lanthanides and actinides
What is the difference between lanthanides and actinides?
Wht is the difference between Lanthanides and Actinides?
What are the elements of 4F series called?
The 4f series is referred to as the Lanthanides.
What about the complex formation ability of lanthanides as campared to actinides?
describe the complex formation by lanthanides?
What section of the periodic table is the 4f subshell being filled?
Atoms first occupy the 4f level in the Lanthanide series, beginning with Cerium (Ce).
What elements located from cerium to lutetium?
These are the lanthanides or the 4f block; they should include lanthanum were it not for a contraction that lags lanthanum in the d block.
Do actinides and lanthanides lose electrons when combining?
Actinides and lanthanides lose electrons and form cations.
Why are lanthanides in period six and actinides in period 7?
Lanthanides have 6 electron shells. Actinides have 7 electron shells.
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.
