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.
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.

The noble gas configuration of Mg2+ is [Ne] because the magnesium atom loses two electrons to form the Mg2+ ion. The electron configuration of Ne is 1s2 2s2 2p6, so when Mg loses its two valence electrons, it achieves a stable electron configuration similar to that of the noble gas Ne.
All halogens have 7 valence electrons. They gain one electron and achieve noble gas electronic configuration
P3-
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.
[Ne] 3s2 3p3
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.
K+
P 3- is the ion with the noble gas configuration.
Potassium loses one electron to form K+ ion that has the noble gas configuration of the element neon.
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.
When potassium achieves a noble gas electron configuration, it loses one electron to form the K+ ion. The K+ ion has a stable electron configuration similar to that of argon, with 18 electrons.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
