What is the oxidation state of sulfur in SO3?

1 answer:

8 0

The oxidation state of a substance is the electric charge it is exhibiting in a given state. This may be determined by looking at the oxidation states of accompanying atoms as well as the charge on the complete molecule.

In this case:

Molecular charge: 0
Oxidation state of oxygen: -2 (it is a group 6 element)

Thus,

S + 3 * -2 = 0
S = 6

Sulfur is exhibiting an oxidation state of +6.

What happens to the atomic radius when an elctron is lost

Daniel [21]

Answer:

It decreases.

Explanation:

Due to changes in the Coulombic force, the protons within the nucleus of the ion have a much easier time pulling at one fewer electrons. This way, the electrons are pulled closer to the center, causing the radius to decrease.
