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-.
K+And the K ion configuration is 1s2 2s2 2p6 3s2 3p6Noble gases have the configuration up to 3p6Pseudo noble gases have it up to 3d10
it would be probably 2-.
Argon. Calcium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2, and when it loses its valence electrons (the outermost 4s2 electrons) it has a configuration identical to argon. If you don't know about sublevels, then disregard that. Calcium has a configuration of 2-8-8-2, and when it loses its 2 valence electrons, it has a configuration identical to argon in the ground state. Hope that cleared it up
sulfur has 16 electrons with a neutral charge the most common ion formed is the sulfide ion, with a negative 2 charge to get a negative 2 charge, it gains 2 electrons, thus fulfilling the octet rule and acquiring the electron configuration of argon

P-3 ion is formed with 18 electrons.
Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+

Na+ ion.
P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+
