Are group 12 on the periodic table lanthandies or actinides?
Group 12 elements on the periodic table are not lanthanides or actinides. They are transition metals, also known as the zinc group, which includes elements like zinc (Zn), cadmium (Cd), and mercury (Hg). Lanthanides and actinides are separate groups that are located in the inner transition metals section of the periodic table.
Why are there two rows of elements below the periodic table?
The two rows below the main periodic table are the lanthanides and actinides. These elements are placed separately to prevent the table from becoming too wide. Lanthanides start at atomic number 57, while actinides start at atomic number 89.
What are the lanthanides and actinides found on the periodic table?
They are found below the periodic table because they would take up too much room in the periodic table
Where do you find the anthanides in the periodic table?
As a start, try writing them as the "lanthanides". This group consists of the fifteen elements from lanthanum, with atomic number 57, through and including lutetium, with atomic number 71. In most periodic tables, they are in a separate row at the bottom of the table, often with a footnote reference at the spot on the table between barium and hafnium.
What name each column or group of the periodic table?
The columns of the periodic table are known as groups or families. There are 18 groups, with notable names including Group 1 (Alkali Metals), Group 2 (Alkaline Earth Metals), Group 17 (Halogens), and Group 18 (Noble Gases). The transition metals occupy groups 3 to 12, while the lanthanides and actinides are separate rows placed below the main table. Each group shares similar chemical properties and reactivity.

Why are the elements 57 through 70 and eighty through 102 found separate from the top of the periodic table?
These elements are termed as 'lanthanides' and 'actinides' have certain different characteristics that cannot be fitted into modern periodic table,hence they are placed at the bottom.
Why are two of the rows of the periodic table deprecated from the rest of the chart?
The two rows at the bottom of the periodic table, known as the f-block, are separated to conserve space. They contain the lanthanides and actinides series of elements and would make the rest of the periodic table too wide if included. These rows are still part of the periodic table, but they are usually shown below as a separate section for convenience.
What are the lanthanides and actinides found on the periodic table?
They are found below the periodic table because they would take up too much room in the periodic table
What is the period for plutonium in the periodic table?
It is in the actinides period (separate lower section of Period 7).
Why are lanthanides difficult to separate?
Lanthanides are difficult to separate because they have very similar chemical properties due to the filling of 4f orbitals, making them hard to distinguish. This similarity makes conventional separation methods less effective, requiring more complex and costly techniques such as solvent extraction or ion exchange to separate them effectively.
What is a characteristic of the lanthanides?
One characteristic of the lanthanides is their similar physical and chemical properties due to the presence of partially filled 4f orbitals. This makes it challenging to separate and distinguish between the different lanthanide elements.

How Cerium can be separated from the solution of lanthenides?
Cerium can be separated from lanthanides by controlling the pH of the solution. Cerium typically exists in solution at a different pH range compared to other lanthanides, allowing for selective precipitation or solvent extraction to separate it from the rest of the group. Additional techniques such as ion exchange or chromatography can also be employed for further purification.
