In an ion, the sum of the oxidation states is equal to the overall ionic charge. note that the sign of the oxidation states and the number of atoms associated with each oxidation state must be considered. in oh−, for example, the oxygen atom has an oxidation state of −2 and the hydrogen atom has an oxidation state of +1, for a total of (−2)+(+1)=−1. what is the oxidation state of an individual sulfur atom in so32− ?

the oxidation state of an individual sulfur atom in SO₃⁻² is +4.

Explanation:

1) Fundamental considerations: There are important rules that you need to know to find the oxidation states of neutral compounds or ions.

In a neutral compound the sum of the oxidation states is equal to zero. In an ion, the sum of the oxidation states is equal to the overall ionic charge.Except in peroxides, oxygen (O) atoms bonded to other atoms have oxidation state -2.

Those are the relevant rules for this question.

2) Procedure:

The ion for which you have to fiind the oxidation state of an indivitual sulfur atom is SO₃⁻².Let x be the oxidation state of the sulfur (S) atom.Oxidation state of O = -2Total oxidation number for 3 atoms of O: 3 × (-2) = - 6Overall ionic charge of SO₃⁻²: - 2Sum of the oxidation states: x + (-6) = overal charge⇒ x + (-6) = -2Solve for x: x = - 2 + 6 = + 4

4) Conclusion: the oxidation state of an individual sulfur atom in SO₃⁻² is +4.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
