Atomic sulfur has oxidation number 0. The oxidation number of the sulfide ion is -2. During formation of a wide variety of compounds, the oxidation status of sulfur may differ from -2 to +6.
The oxidation number of sulphur in H2S is 2.
Oxidation no of sulphur is +2.
6+
+4 for carbon, -2 for each Sulphur
-2 for each O, +6 for S
The oxidation number of sulphur in H2S is 2.
Sulphur has 6 valence electrons. So its maximum oxidation number is +6.
Oxidation no of sulphur is +2.
6+
The oxidation number in atomic sulfur is 0. The oxidation number of sulfide ion is -2. With oxygen and other non metals, it makes numerous ions where its oxidation number varies from -2 to +6.
Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
+4 for carbon, -2 for each Sulphur
+1 for each H and -2 for sulphur
-2 for each O, +6 for S
-2 for each sulphur; +3 for each aluminium
Generally for group 16 elements, like oxygen, sulphur, selenium.
Number for hydrogen is +1.Number for sulphur is +6.Number for oxygen is -2.The oxidation number for the overall ion is -1. Oxidation numbers for hydrogen and oxygen are +1 and -2 respectively. By balancing the charges, the sulfur atom is in +6 state.
