What is the oxidation number of Sulphur atom in Na_(2)S_(2)O_(3) (Na: 1 A group . 0: 6A group). A) -2 B) +4 C) +2 D) +3 E) -1

To find the oxidation number of sulfur in , we can use the following steps:1. Assign oxidation numbers to the elements based on their group numbers: - Sodium (Na) is in group 1A, so its oxidation number is +1. - Oxygen (O) is in group 6A, so its oxidation number is -2.2. equation based on the sum of oxidation numbers: The sum of the oxidation numbers of all atoms in a neutral compound is zero. In this case, we have: 3. Substitute the known oxidation numbers into the equation: 4. Solve for the oxidation number of sulfur: Therefore, the oxidation number of sulfur in is +2.The correct answer) .
