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 combustible gases located in a water tube boiler?
In a water tube boiler, combustible gases are primarily located in the combustion chamber and flue gas passages. The combustion chamber is where the fuel is burned, producing hot gases. These gases then flow through the flue gas passages, transferring heat to the water in the tubes before being expelled through the exhaust stack. Proper management of these gases is essential for efficient operation and safety.

How variables are the densities of the lanthanides compared to the densities of the actinides?
The lanthanides generally have higher densities than the actinides. This is because lanthanides are located in period 6 of the periodic table, where atomic size decreases from left to right, leading to higher densities. In contrast, actinides are located in period 7, where atomic size is larger and densities are lower on average.
What elements located from cerium to lutetium?
The elements located from cerium to lutetium in the periodic table are known as the lanthanides. They have atomic numbers 58 to 71 and are characterized by similar chemical properties. Lanthanides are used in various technologies such as electronics, lasers, and renewable energy applications.
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.
