What is the oxidation number for XeO3?

Answer 1

If the atom is neutral, the number of protons equal the number of electrons. The number of protons can be found by the mass number of the specific atom.

For Xe the mass number is 54, therefore there are 54 protons, and 54 electrons.

Answer 2

If Xe2 existed, which it doeesn't as this would be an allotrpe of an elemnt the oxidation number is zero.

Xe2+ may exist- the average oxidation state of Xe is +1/2

Answer 3

-1 for each F, -2 for each O, +6 for Xe

Answer 4

Since each fluoride anion always has one net negative charge, element X must have two net positive charges to provide electrical neutrality for compound XF2.

Answer 5

The oxidation number is 0.

Answer 6

+1 for H

-2 for O

+6 for Xe

Answer 7

-2 for each O and +6 for Xe
