The electron configuration of sulfur is [Ne]3s23p4.
Sulfur typically forms a -2 ion (S²⁻) by gaining two electrons. The electron configuration for a neutral sulfur atom is 1s² 2s² 2p⁶ 3s² 3p⁴. For the S²⁻ ion, the electron configuration becomes 1s² 2s² 2p⁶ 3s² 3p⁶, which is the same as that of argon, indicating that it has achieved a stable noble gas configuration.
Sulfide, S2-
The electronic configuration of sulfur ion (S)2- is: 1s22s22p63s23p6.
Se2- 1s22s22p63s23p64s23d104p6
The electron configuration of selenium (Se) is [Ar] 3d10 4s2 4p4. To form a 2- ion, two electrons will be removed from the outermost shell, which is the 4p subshell. Therefore, the electron configuration of Se2- is [Ar] 3d10 4s2.
When sulfur forms a negative ion, it gains two electrons to achieve a full outer electron shell, making it have the same electron configuration as argon.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
Sulfur ion typically has a 2- charge (S^2-) due to gaining two electrons to achieve a stable electron configuration. Chlorine ion usually has a 1- charge (Cl^-) by gaining one electron to reach a stable electron configuration. Energetically, sulfur ion tends to form compounds with metals in higher oxidation states compared to chlorine ion.
Sulfide, S2-
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
The electron configuration of Thallium III ion (Tl3+) is [Xe] 4f14 5d10, where [Xe] represents the electron configuration of xenon (54 electrons) which precedes thallium on the periodic table. Thallium loses 3 electrons to achieve a noble gas configuration.
The abbreviated electron configuration for Pt is [Xe] 6s1 4f14 5d9. also, the configuration for Pt2+ ion is [Xe] 4f14 5d8
When a sulfur atom gains two electrons to become a sulfide ion, it achieves a stable electron configuration with a full valence shell. This results in the formation of a negatively charged ion with a 2- charge. A sulfide ion forms due to electron transfer, creating a more stable configuration for the sulfur atom.
