The noble gas electronic configuration of iron is
[Ar] 3d6 4s2
When phosphorus achieves a noble gas configuration, it gains three electrons to become the phosphide ion (P³⁻). This allows it to achieve the stable electron configuration of a noble gas, similar to argon.
Oxide ion (O²⁻) has the electron configuration of a noble gas neon (Ne), which is 1s² 2s² 2p⁶.
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.
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.
The pseudo-noble gas configuration for calcium is achieved when it loses two electrons to form a Ca2+ ion. This results in the same electron configuration as argon.

Oxide ion (O²⁻) has the electron configuration of a noble gas neon (Ne), which is 1s² 2s² 2p⁶.
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.
P 3- is the ion with the noble gas configuration.
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.
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.
The noble gas configuration for potassium is [Ar] 4s^1. To form a cation, potassium would lose its one valence electron, resulting in a 1+ ion. Therefore, the ion formed when potassium achieves a noble gas electron configuration is K^+.
The pseudo-noble gas configuration for calcium is achieved when it loses two electrons to form a Ca2+ ion. This results in the same electron configuration as argon.
[Ar] 4s2 3d3
No, chlorine (Cl) does not have a noble gas electronic configuration. It has the electron configuration [Ne]3s^2 3p^5, which is one electron away from achieving a stable, noble gas configuration like argon (Ar).
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
The noble gas configuration for bromine's ion (Br-) is [Kr] 4d10 5s2 5p6, which is equivalent to the electron arrangement of krypton. Bromine gains an electron to achieve a stable octet configuration like a noble gas.
