Neon
Krypton is the noble gas with 3 energy levels. It has electronic configuration [Ar] 3d10 4s2 4p6.
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration.
Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.
The valence shell (outermost energy level) of a noble gas is filled in ... ns2 np6 electron configuration except helium where it is 1s2.

The noble gas elements have outermost energy levels with full s and p orbitals.

No. The noble gases are largely nonreactive because their outermost energy levels are complete, making them stable by themselves.

The element is 'argon' and belongs to noble gas family.
Fluorine... it has seven valence electrons and really wants to achieve noble gas configuration (8 out of 8 possible valance electrons). It already has seven and since it is so close to eight, it is very attached to them. It refuses to give them up easily. The more an element "wants" it's electrons the higher ionization energy it will have. http://www.800mainstreet.com/4/0004-002-Periodic.html
No noble gas possesses 6 electrons in the 6th energy level. Noble gases have a stable electron configuration with a full valence shell. Helium has 2 electrons in its first and only energy level, while neon has 10 electrons in its second energy level.
Pseudo noble gas configurations for cations are achieved by removing electrons from the highest energy levels first. For example, for the cation Na+, the electron configuration can be represented as [Ne]3s1, where Ne represents the noble gas neon. This notation helps to show the remaining electrons in a shortened manner.
The noble gas configuration for germanium is [Ar] 3d10 4s2 4p2. It is written this way because germanium has 32 electrons, and the electron configuration is based on filling up orbitals in order of increasing energy levels, similar to the noble gas argon, which has 18 electrons in its outermost shell.
