Because noble gases were not discovered at that time.
Because noble gases were not discovered when Mendeleev formulated his periodic table
Noble gases are found in the 18th group in the periodic table.
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.
The noble gases are located in Group 18 of the periodic table. They are known for being chemically inert and have a full valence shell of electrons, making them very stable and unreactive. The noble gases include helium, neon, argon, krypton, xenon, and radon.
Noble gases are in the group 18 of the periodic table of Mendeleev.

Noble gases.
The noble gases are located in Group 18 of the periodic table. They are known for being chemically inert and have a full valence shell of electrons, making them very stable and unreactive. The noble gases include helium, neon, argon, krypton, xenon, and radon.
The noble gases are a group of elements in the periodic table known as Group 18. These gases are colorless, odorless, and have low reactivity due to their stable electron configuration. Examples include helium, neon, argon, krypton, xenon, and radon.
That's correct! Group 18 on the periodic table is known as the noble gases. These elements have full outer electron shells, making them highly stable and unreactive under normal conditions. The noble gases include helium, neon, argon, krypton, xenon, and radon.
There are 6 noble gases in periodic table. The common one is helium.
Neon is a noble gas located in period 2 on the periodic table.
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).
Group-17 is the nearest neighbor to the noble gases in the periodic table.
