[Kr]4d105s25p5
The noble gas that comes before iodine is krypton.
No, 3s2p3 is not the noble gas distribution for phosphorus. Phosphorus has an electron configuration of 1s2 2s2 2p6 3s2 3p3, which is not a noble gas distribution. Noble gas distribution for phosphorus would be [Ne] 3s2 3p3.
The nearest noble gas to iodine is xenon. Iodine is located in group 17 of the periodic table, while xenon is in group 18. Xenon has an atomic number of 54, making it the closest noble gas in terms of atomic number.

No, iodine is not a noble gas. Iodine belongs to the halogen group in the periodic table, which contains elements that are highly reactive. Noble gases are a separate group of elements that are inert and do not readily combine with other elements.
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 is not a "nobel" gas or even a noble gas but rather a nonmetal element that is not a gas at all at standard temperature and pressure, but a solid instead. -- Unlike the elements in the noble gas group such as neon, which are chemically very unreactive, iodine is quite reactive, like the other elements in its group such as fluorine and chlorine.
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)

The element between tellurium and xenon is iodine. It has an atomic number of 53.
