It is the electron orbital configuration of the outer level of 18Argon atom or 19K+ ion.
The complete electron configuration for the chromium(III) ion is 1s22s22p63s23p64s03d3.
The configuration Ne 3s2 3p6 represents the electron configuration of the noble gas neon, which has 10 electrons in total.
Calcium has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2.
1s2 2s2 2p6 3s2 3p6
1s2, 2s2 2p6, 3s2 3p6 The sulfur ion has 16 electrons but sulfide has a charge of negative 2, increasing its electron count by two for a total of 18 electrons, giving it the same electron configuration as Argon (this means it is also isoelectronic with Argon)
