Neon belongs to group 18 and period 2 of the modern periodic table.

Example of noble gas group. Helium is obtained from Natural Gas Wells. For example Helium and Radon the topmost and bottommost elements of the Noble Gases Group are not found in the air. However in many ionic compounds the cations do not attain noble gas configuration an octet configuration as described below.

As with the rare earths the rare gases arent particularly uncommon. The noble gas atoms as do the atoms in most other groups on the periodic table increase steadily in atomic radius from one period to the next due to an increasing number of electrons. Read in-depth answer here.

The noble gases are a group of non-metals consisting of helium neon argon krypton xenon and radon. The VIII A group of elements in the periodic table consists of He Helium Ne Neon Ar Argon Kr Krypton Xe Xenon and Rn Radon. The six naturally occurring noble gases are helium He neon Ne argon Ar krypton Kr xenon Xe and the radioactive radon Rn.

Pseudo-noble gas configuration which can also be called pseudo inert configuration is when elements have fully filled d-orbital along with s - and p - orbitals. The Noble Gases Group 18 It has been possible to prepare only a few hundred noble gas compounds. Examples of noble gas compounds include argon fluorohydride HArF and xenon hexafluoride XeF 6.

Al3 takes up the configuration of Neon when it loses its 3 valence electrons. I For some elements Cu Ag Au Zn Cd Hg In and Tl all outer shell electrons are ionized. Group 18 of the modern periodic table consists of noble gases.

They are also called. Considering this what is a noble gas for kids. The noble gas atoms as do the atoms in most other groups on the periodic table increase steadily in atomic radius from one period to the next due to an increasing number of electrons.
