Why did Mendeleev's periodic table not contain the noble gases?
Because noble gases were not discovered when Mendeleev formulated his periodic table
Do gases make up most of the periodic table?
no - gases are few in number - metals make up most of the periodic table
What are Helium and neon classified as on the Periodic table?
these gases are the noble gases or inert gases. They are non reactive and have stable valence electrons
What are the other gases?

What are the least active elements in the periodic table?
its the noble gases that are the least reactive group among the elements; and they occupy the left most group i.e. 18th group in the Periodic Table.
How did Dmitri Mendeleev discover the periodic table with noble gases?
Dmitri Mendeleev did not discover the noble gases as they were not known at the time he created the periodic table. The noble gases were discovered later by other scientists. Mendeleev's periodic table focused on arranging elements by atomic mass and properties to show periodic trends.
What is the last group in the periodic table called?
There are no 'rows' on the Periodic Table of the Elements.I assume you are talking about Group-18 of the table.Group-18 of the Periodic Table of the Elements are the noble gases. These elements have a full valence shell (8 electrons).
Where are the inert noble gases located in the Periodic Table?
group 18, the right most group on the periodic table
Is there only solids and gases on the periodic table?
The periodic table contain solid, liquid and gaseous chemical elements.
What are the state of the periodic table?
Periodic table is an arrangement of elements and the elements could be either solid or liquids or gases.
What in the periodic table contain all the gases?
Group 18 or noble gases.
