To determine the oxidation state of the second element in SO3, we need to examine the oxidation states of the other elements and the overall charge of the compound.
In SO3, the oxidation state of oxygen (O) is usually -2, as oxygen is highly electronegative and tends to gain two electrons to achieve a stable octet.
The compound SO3 has no overall charge, meaning the sum of the oxidation states of all the elements must be zero.
The formula for the compound is SO3, so we can represent sulfur's oxidation state as "x." Since there are three oxygen atoms in SO3, the total oxidation state contributed by the oxygen atoms is -2x (3 * -2x = -6x).
Therefore, the sum of the oxidation states of sulfur and oxygen must be zero:
x + (-6x) = 0
Simplifying the equation:
-5x = 0
Dividing both sides by -5:
x = 0
Hence, the oxidation state of the second element (sulfur) in SO3 is 0.
