[Kr]4d^10 5s^2 5p^5
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
Iodine accepts one electron to achieve noble gas configuration. Strontium loses two electrons to achieve noble gas configuration. Nitrogen accepts three electrons to achieve noble gas configuration. Krypton already has a noble gas configuration.
Iodine will gain one electron to form iodide anion which has the electronic configuration of the nearest noble gas (xenon): [Kr] 5s2 4d10 5p6 or 2, 8, 18, 18, 8.
There is no noble gas configuration for hydrogen.
The noble gas that comes before iodine is krypton.

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.
