Fe3+ = = 1s2, 2s2, 2p6, 3s2 , 3p6 , 3d5
(S2- = = 1s2, 2s2, 2p6, 3s2, 3p2) As the S2- ion has gained to electrons not lost them, it now has 18 electrons not 14, Thus:
S2- = 1s2, 2s2, 3p6, 3s2, 3p6
[Ar] 4s2 3d4
This is incorrect.
The correct answer is [Ar] 3d6 because the 4s orbital is the outer shell. The electrons will leave the 4s shell before they will leave the 3d shell.

Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^6 Short-hand version: [Ar] 4s^2 3d^6 Note: The "^" symbol means the the following number is in the form of a superscript.

Phosphorus To determine an element from its electron configuration, simply add up the superscript numbers (those are the numbers of electrons in each sublevel): 1s22s22p63s23p3: 2+2+6+2+3=15, and find the element with the matching atomic number*. In this case, Phosphorus. *Note: This method is not correct if the electron configuration of an ion is given, as the number of electrons in an ion does not match its atomic number.
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The electron configuration of curium is [Rn]5f7.6d1.7s2.
Iron 2 is Fe 2+ and has electron configuration [Ar] s1d5 Iron 3 is Fe 3+ and has electron configuration [Ar] d5
Iron's atomic number is 26. Thus it has 26 protons and 26 electrons. The electronic configuration for the first 26 electrons, and so therefore iron, is Fe 1s2 2s2 2p6 3s2 3p6 4s2 3d6. The shorthand electron configuration is Fe [Ar] 4s2 3d6.
Fe, or iron, has the atomic number of 26. Its full orbital diagram is 1s2 2s2 2p6 3s2 3p6 4s2 3d6.
