No, the electron configuration for an ion is not always the same as that of its nearest noble gas. When an atom loses or gains electrons to form an ion, its electron configuration changes. For example, a sodium ion (Na⁺) has the electron configuration of [Ne], which is the same as neon, but a chloride ion (Cl⁻) also has the same configuration as argon ([Ar]). Thus, while some ions can have configurations similar to noble gases, this is not universally true for all ions.
A noble gas electron configuration involves representing an element's electron configuration by using the electron configuration of the nearest noble gas preceding it in the periodic table, followed by the remaining electron configuration for that element. For example, the noble gas electron configuration for sodium (Na) is [Ne] 3s¹, where [Ne] represents the electron configuration of neon leading up to sodium.
The charge of a sulfide ion that is isoelectric with its nearest noble gas (argon) is -2. This means that the sulfide ion has gained two electrons in order to have the same electron configuration as the noble gas.
Argon has the same electron configuration as N3. Both have 10 electrons with the electron configuration 1s2 2s2 2p6.
Potassium can lose one electron from its outer shell to achieve a stable electron configuration similar to argon. Fluorine can gain one electron to fill its outer shell and attain a stable electron configuration like neon. In both cases, the atoms are trying to achieve a full valence shell and become stable like the nearest noble gas.
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 electron configuration of cesium in noble gas form would be [Xe] 6s^1. This indicates that cesium has the same electron configuration as the noble gas xenon in addition to one extra electron in the 6s orbital.
Zirconium (Zr) has the same noble gas electron configuration as Krypton (Kr). In its electron configuration, Zr has 36 electrons, which corresponds to the 36 electrons of Kr, representing the filled outer electron shells characteristic of noble gases.

Barium has 2 electrons in its outer shell. In order to achieve a noble gas electron configuration it needs to lose these 2 electrons. This will leave it with the same electron configuration as Xenon, a noble gas.
Krypton has the same electron configuration as phosphorus in a PCl3 molecule. Both have the electron configuration of [Ne] 3s^2 3p^3.
Sulfur must lose six electrons to attain noble gas electron configuration (in SO3, H2SO4 etc) but in most of the compounds it will exist as sulphides which is formed when sulphur will gain two electrons.
