The atomic size would increase as you move down anywhere on the table-even the noble gases and as you move to the right. This happens because the higher the atomic number, the higher the protons and electrons, and the more repulsive force. The protons keep pushing out the electrons, therefore making a bigger atom!:D
Because noble gases were not discovered when Mendeleev formulated his periodic table
Helium, neon, and argon are the only elements that exist in nature as isolated atoms, due to their stable electronic configurations that do not readily form chemical bonds with other elements. These elements are known as noble gases for their inert nature.
Noble gases are in the group 18 of the periodic table of Mendeleev.
No, noble gases were not shown in the periodic table of 1869 because they were not discovered until late 19th and early 20th centuries. Helium was the first noble gas to be discovered in 1895, followed by other noble gases such as neon, argon, krypton, and xenon.
Noble Gases: Because Noble Gases are already in a stable form, they are not as likely to bond with other atoms as are those farther from a stable form. Noble Gases are found in group VIII, which is the far rightmost column.
The noble gases in group 18 are inert.
Atoms try to imitate the noble gases in the periodic table by changing their electrons. Noble gases have stable electron configurations, so other atoms will gain, lose, or share electrons in order to achieve a similar stable configuration like the noble gases.

Noble gases.

The noble gases are located on the far right column of the periodic table.
Neon is a noble gas located in period 2 on the periodic table.
The noble gases usually have an octet on the periodic table. They have a full outer shell of electrons, making them stable and unreactive.

helium is in the family of noble gases according to the periodic table
