"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the Periodic Table (in brackets).
For example, the noble gas configuration of nitrogen is [He]2s22p3
There is no noble gas configuration for hydrogen.
Krypton is a noble gas and already has noble gas configuration.
The noble gas configuration for manganese is [Ar]4s23d5
The noble gas electron configuration of radon is [Xe]4f145d106s26p6.
Krypton is already a noble gas and hence need not gain noble gas configuration.
There is no noble gas configuration for hydrogen.
Krypton is a noble gas and already has noble gas configuration.
The noble gas configuration of strontium is [Kr]5s2.
The noble gas configuration for manganese is [Ar]4s23d5
The noble gas electron configuration of radon is [Xe]4f145d106s26p6.
Krypton is already a noble gas and hence need not gain noble gas configuration.
The "Noble gas electron configuration," or the condensed electron configuration, for F is [He] 2s2 3p5.
The element chlorine does not have noble gas configuration. But chloride ion formed (when chlorine accepts an electron) has noble gas configuration of argon.
Only group 18 elements have noble gas configuration. All other elements lack a noble gas electronic configuration.
Definition: A noble gas core is an abbreviation in an atom's electron configuration where the previous noble gas's electron configuration is replaced with the noble gas's element symbol in brackets. ... This is the noble gas core notation of sodium.
Full form: 1s1. it doesn't have noble gas configuration as there is no noble gas before hydrogen
The electronic configuration of Ga is 1s22s22p63s23p64s23104p1 Expressed as a noble gas configuration this is [Ar] 4s2, 3d10, 4p1
