O2- has 10 electrons with the configuration of neon or 1s2 2s2 2p6
A noble gas electronic configuration has an outer shell of ns2, np6. Examles of ions with this configuration are O2- [He], 2s2 2p6 (the neon configuartion) Cl- [Ne] 3s2 3p6 (the argon configuration)
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.
The electron configuration for an O2- ion is 1s22s22p6 just like the noble gas neon.
A noble gas electronic configuration has an outer shell of ns2, np6. Examles of ions with this configuration are O2- [He], 2s2 2p6 (the neon configuartion) Cl- [Ne] 3s2 3p6 (the argon 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.
Full form: 1s1. it doesn't have noble gas configuration as there is no noble gas before hydrogen
