Using only the information available in the periodic table, consider the elements sulfur and oxygen. from their location on the periodic table, identify the oxidation state and number of valence electrons for sulfur and oxygen. then use this information to describe their reactivity.

which statement most accurately describes the compound formed by sulfur and oxygen?

a) sulfur dioxide, so2, is ionic, formed between sulfur and oxygen ions.

b) sulfurous oxide, so2, is ionic, formed by the ionic bonding of sulfur and oxygen.

c) sulfur monoxide, so, is covalent, formed by the sharing of electrons between sulphur and oxygen.

d) sulfur dioxide, so2, is covalent, formed by the sharing of electrons

Option D

Explanation:

In Sulphur dioxide molecule both sulphur and oxygen have 6 valence electrons

The oxidation state of Sulphur in Sulphur dioxide molecule is +4 and the oxidation state of oxygen in Sulphur dioxide molecule is -2

Both sulphur and oxygen in this molecule are non-metals and therefore there will be no ionic bond present between them

So bond formation in this molecule takes through sharing of electrons between sulphur and oxygen and due to the sharing of electrons, covalent bond formation takes place between them

As there are only covalent bonds involved, this molecule is a covalent molecule

∴ Sulphur dioxide molecule is covalent and formed by the sharing of electrons

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
