Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
The ion formed when potassium achieves noble-gas electron configuration is K+ (potassium ion). This occurs when potassium loses one electron to have a full outer electron shell, similar to the nearest noble gas, argon.
There is no chlorine chloride. The formula for a molecule of chlorine is Cl2.
No, it is is not. A cation is always formed by losing an electron while bromide is an anion formed by gaining an electron. By rahul
The element with a valence electron configuration of ns2 np4 is sulfur (S). Since it needs to gain 2 electrons to achieve a stable electron configuration, it is most likely to form an ion with a charge of -2.
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.

Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+
P-3 ion is formed with 18 electrons.
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.
The ion formed when sodium achieves a noble-gas electronic configuration is Na+. This means that sodium has lost one electron to achieve the same electron configuration as neon, a noble gas, which has a stable electron configuration.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
Na+ ion.
P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
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.
