Question

What is the noble gas notation for neon?

Answer 1

Noble gases are also known by the name of inert gases and these gases are the chemical compounds which belong to group 18 of the periodic table. Noble gases was discovered by Sir William Ramsay in which the last element of noble gases i.e. radon is radioactive in nature.

Complete answer:
Noble gases are gases whose valence shell is completely filled where the valence shell corresponds to the shell in which the last electron of an atom fills. Electronic configuration tells us about the distribution of electrons of an atom or molecule in atomic or molecular orbitals. Electronic configuration was first discovered through the Bohr model of the atom which generally describes shells and subshells.
Neon is the chemical element represented by $Ne$ having atomic 10. So its electronic configuration is $1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}$. Now to write neon using noble gas notation we first come to know that which noble gas element is written here as neon is also kept in the category of noble gases so noble gas having atomic number less than it will be write here which is helium and having electronic configuration $1{{s}^{2}}$ this is represented by the symbol $He$.
Hence the electronic configuration for neon using noble gas notation $[He]2{{s}^{2}}2{{p}^{6}}$.

Note:
There are six naturally occurring noble gases which are helium, neon, argon, krypton, xenon and radon. Noble gases are meant to be less reactive in nature as their valence shell is completely filled so the electrons will move to the next available shell which needs a very high amount of energy.
