P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
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.
P3-
K+
Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+
s2,s2 p6.s1
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-.
P-3 ion is formed 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.
Sodium achieves the neon gas onfiguration 1s2 2s2 2p6 and the ion is written as Na+. Sodium can form many stable compounds by ionic bonding.
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.
