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.
There is no noble gas with the same electronic configuration as the element barium (Ba). But Ba2+ ion and the noble gas xenon (Xe) will have the same number of electrons (54 electrons each).
The noble gas configuration for zinc is [Ar] 3d10 4s2. This means that zinc has the same electron configuration as the noble gas argon, and then has two more electrons in the 4s orbital.
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
The noble gas configuration of magnesium is [Ne] 3s^2. This indicates that magnesium has the same electron configuration as the nearest noble gas, neon, with an outer shell containing 2 electrons in the 3s orbital.

[He]2s22p4
The noble gas configuration for zinc is [Ar] 3d10 4s2. This means that zinc has the same electron configuration as the noble gas argon, and then has two more electrons in the 4s orbital.
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
The noble gas configuration of magnesium is [Ne] 3s^2. This indicates that magnesium has the same electron configuration as the nearest noble gas, neon, with an outer shell containing 2 electrons in the 3s orbital.
The calcium ion formed when it achieves a noble-gas electron configuration is Ca2+, as it loses two electrons to have the same electron configuration as argon, a noble gas.
The noble gas configuration for selenium is [Ar] 3d10 4s2 4p4, which means it has the same electron configuration as argon, followed by 4d10 4p4 electrons.
The noble gas configuration for manganese (Mn) is [Ar] 3d5 4s2. This means that it has the same electron configuration as argon (Ar) with 18 electrons, followed by 3d5 and 4s2 orbitals filled with electrons.
neon
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 noble gas electron configuration of radon is [Xe]4f145d106s26p6.
