Because nitrogen is more electronegative than all elements except fluorine, oxygen, and chlorine, it exhibits positive oxidation states only in combination with these three elements. Can you explain this answer? Ans: Nitrogen valence electronic configuration ns2np3 due to absence empty d- orbitals, it can not extend its valence to 5 2. This is often known as the inert pair effect - and is dominant in lead chemistry. Older method • add suffix “ic” to element’s Latin name for higher oxidation state • add suffix “ous” to element’s Latin name for lower 2. Performance & security by Cloudflare, Please complete the security check to access. As you get closer to the bottom of the Group, there is an increasing tendency for the s 2 pair not to be used in the bonding. Because of the stability of the N≡N triple bond, it requires a great deal of energy to make compounds from molecular nitrogen. 2.3k VIEWS. Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic , with no covalent component. While sulphur dioxide and hydrogen peroxide can act as an oxidising as well as reducing agents in their reactions, ozone and nitric acid act only as oxidants. 1:27 1.2k LIKES. • 7.

Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Others, notably the nonmetals and the transition elements, can assume a variety of oxidation numbers; for example, nitrogen can have any oxidation number between −3 (as in ammonia, NH 3) and +5 (as in nitric acid, HNO 3). Practice and master your preparation for a specific topic or chapter. The substances where nitrogen can exhibit oxidation states from –3 to +5 are listed in the following table. The Questions and Oxidation state indicates the degree of oxidation for an atom in a chemical compound; it is the hypothetical charge that an atom would have if all bonds to atoms of different elements were completely ionic. Explain. (A) N2O < N2O3 < NO2 < N2O5 < NO ( The oxidation number is synonymous with the oxidation state. Apart from being the largest Class 10 community, EduRev has the largest solved The +5, 0, and -3 oxidation states are the most common and generally the most stable of these.

Suggest a list of substances where carbon can exhibit oxidation states from -4 to +4 and nitrogen from -3 to +5. There are no stable oxyacids containing nitrogen with an oxidation state of 4+; therefore, nitrogen(IV) oxide, NO 2, disproportionates in one of two ways when it reacts with water. Warning: Don't fall into the trap of quoting CH 4 as an example of carbon with a typical oxidation state of +4. (b) Ferrous compounds are less volatile than the corresponding ferric compounds. Its designated by noting the charge on the atom after theoritically giving the bonded electrons in a bond to the more electronegative element. Nitrogen is the chemical element with the symbol N and atomic number 7. Actually this fractional oxidation state is the average oxidation state of the element under examination and the structural parameters reveal that the element for whom fractional oxidation state is realised is present in different oxidation states. For example, the formula of magnetite is Fe 3 O 4 , implying an average oxidation state for iron of + 8 / 3 . In the case of phosphorus, the intermediate oxidation states disproportionate into +5 and -3 in both acids and alkalis. But we don’t say “the oxidation state of oxygen is -4” because there are two of them; they average to -2.
