Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
the noble gases are the least reactive(thats group 18) followed by group 14
Group 18 or Noble gases. As they have completely filled orbitals.
Noble gases are the least reactive elements in the periodic table because they have a full valence shell.The least reactive elements in the periodic table are the noble gases or sometimes the inert gases. These are the elements of Group 18, and they have full valence shells. They are not interested in loaning out or borrowning electrons, and are very stable.The gases helium, neon, argon, krypton, xenon and radon make up the inert gases. Wikipedia has a nice post on these interesting elements, and a link is provided.
The noble gases, they are Helium, Neon, Argon, Krypton, Xenon, Radon, and Ununoctinum.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
No. They are the least because their energy levels are full.

Group 18 or Noble gases. As they have completely filled orbitals.
The noble gases are the least reactive elements on the periodic table. They have a full outer electron shell, making them stable and unlikely to participate in chemical reactions.
Generally, the least reactive elements are the noble gases.

As you move left on the periodic table, the elements get more reactive and as you move down the periodic table. Using that thinking the most reactive elements are the Alkali Earth Metals (column 1) and the most reactive element is Francium. The least reactive are the noble gases in the last column- Helium, Neon, Argon etc..
Nobel gases.
The noble gases, they are Helium, Neon, Argon, Krypton, Xenon, Radon, and Ununoctinum.
Noble gases, the group 18 elements in the periodic table, contain the least reactive elements. They have a full outer electron shell, making them very stable and unlikely to form bonds with other elements.
