There are 7 periods in the modern Periodic Table.
What else can I help you with?
What two groups are removed from the main body of the periodic table?
Lanthanides and actinides are the two groups that are usually removed from the main body of the periodic table and placed below it to conserve space.
What are the sub categories of the periodic table of elements?
The periodic table of elements is divided into groups and periods. The groups (columns) are elements with similar chemical properties, while the periods (rows) represent the number of electron shells in an atom. The main subcategories include metals, nonmetals, and metalloids.
What is the bottom section of the periodic table for?
The bottom section of the periodic table is for the lanthanides and actinides, which are also known as the inner transition metals. These elements are placed below the main body of the periodic table to keep it compact, as they would otherwise disrupt the table's organization.
What are the main metals in the periodic table?
The main metals in the periodic table are iron, copper, zinc, silver, gold, and platinum. Metals are typically found on the left side of the periodic table and are known for their conductivity, malleability, and luster.
Which element family is usually shown separated from the main part of the periodic table?
The lanthanide and actinide series are typically shown below the main part of the periodic table, known as the "f-block." These elements are often separated to keep the table compact, as they are very similar in properties and would make the table much wider if included in the main body.
How many periods are there in main body of periodic table?
7
How many periods are in the main body the periodic tabl?
7 periods.

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 are the three main classes of elements in a periodic table?
Three main classes are:MetalsNon metalsTransition elementsThey are present in periodic table.

How many main groups are there on the periodic table?
8 main groupes, 10 transition metal groupes in periods 4,5,6,7 14 in lanthanides in period 6 14 in actinides in period 7
What are the two rows of metals that appear at the bottom of the periodic table?
The two rows of metals that appear at the bottom of the periodic table are the lanthanides and actinides. They are known as the inner transition metals and are placed below the main body of the periodic table to keep the table size manageable.
What is the main advantages of the periodic table?
It organizes the elements.
