The atomic no for Cu is 29 at ist it loses 2 electrons then accepts 8 or 10 electrons from legands by coordination now it has either 35 or 37 electrons which is very close to the atomic no of krypton a noble gas....
[Ar]3d104s1
yes, Cu+ has a pseudo-noble-gas electron configuration
Argon
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
yes, Cu+ has a pseudo-noble-gas electron configuration
Argon
[Ar]3d104s1
[Ar]4s1 3d10
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.
