Iodine is a non-metal.
It belongs to group 17 (halogen family).
The noble gas that comes before iodine is krypton.
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.
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.
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.

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.

The element between tellurium and xenon is iodine. It has an atomic number of 53.
Iodine gains one electron to achieve a noble gas electron configuration. Its electron configuration is [Kr]5s²4d¹⁰5p⁵, and by gaining one electron, it attains the stable configuration of [Kr]5s²4d¹⁰5p⁶, which is similar to the noble gas xenon.
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.
The atomic symbol of Iodine is "I". If you look on the Periodic table of elements, you can see that Iodine is the only element that uses the atomic symbol "I", which makes it easier to remember.
The element that gains 1 electron to attain the noble gas configuration of Xenon (Xe) is iodine (I). When iodine gains an electron, it achieves a stable electron configuration with a filled outer shell, similar to that of Xenon.
