help please. THANKS!

The oxidation number of an element is the "charge" the element would hay ionic; that is, if the electron pairs of each bond were transferred to the more For monatomic ions the oxidation number is simply the charge of the ion. Fe oxidation number is a bookkeeping device and does not mean that the eleme Determine the oxidation state for each of the elements below. fluorine gas is fluorine gas F2 The oxidation state of fluorine in sulfur trioxide SO3 The oxidation state of sulfur in 1S The oxidation state of in xenon gas is xenon Xe Submit Answer Retry Entire Group 2 more group attempts remaini

Explanation / Answer

Any element in nature exists in two forms; free form also known as the elemental form and combined form (molecules, compounds and ions). If it exists in a free form, it has no charge and if it exists in a combined form, it has a charge. This charge is known as the oxidation number.

In elemental state the oxidation state of the atom is zero. so here F in F2 and Xe in Xe gas both are exist in elemental form so oxidation state of them is Zero.

The sum of the oxidation states of all the elements in molecules or ions must be equal to the charges on the molecules or ions.Neutral molecules do not carry any charges and hence the sum of the oxidation numbers in these molecules must be zero. So SO3 is neutral its sum of oxidation states are equals to zero.

Oxygen most commonly carries oxidation number of -2.

Let us consider the oxidation state of Sulphur is X

X + 3x(-2)=0 (there are 3 oxygens in the molecule each having -2 as charge)

X-6=0

X=+6

oxidation state of Sulphur in SO3 is +6
