Oxidation Numbers req The oxidation number of an element is the "charge" the element would have if all of its bonds were completely ionic; that is, if the electron pairs of each bond were transferred to the more electronegative atom. req req For monatomic ions the oxidation number is simply the charge of the ion. For covalently bonded elements the oxidation number is a bookkeeping device and does not mean that the element carries an actual charge. 1req Determine the oxidation state for each of the elements below 1req nitrogen in nitrogen monoxide is The oxidation state of No bromine gass The oxidation state of bromine in Br2 hydroxylamine The oxidation state of nitrogen in t Treq t 1req Submit Answer Retry Entire Group 9 more group attempts remaining Previous Next Email Instructor Save and Exit

Explanation / Answer

let the oxidation number of unknown be x

No
oxidation number of O = -2
since, it is neutral sum of oxidation number must be 0
x-2 = 0
x = 2
so, oxidation number of N is 2

Br2
since, it is neutral sum of oxidation number must be 0
2x = 0
x = 0
so, oxidation number of Br is 0

NH2OH
oxidation number of O = -2
oxidation number of H = +1
since, it is neutral sum of oxidation number must be 0
x + (3*1) + -2 = 0
x = -1
so, oxidation number of N is -1
