By definition, the oxidation number of an atom is the charge that atom would have if the compound was composed of ions. Cu1+ NO31- 7. Cu(NO3) 2 9. The oxidation number of diatomic and uncombined elements is zero. NiSO4 4. NH41+ P3- 6. CuF2 14. N CaI2 11. The oxidation number of a monatomic ion equals the charge of the ion. 7 Na1+ F1- 1. Exceptions include OF 2 because F is more electronegative than O, and BaO 2, due to the structure of the peroxide ion, which is [O-O] 2-. ______________________ 8. Roman Numerals in Ionic Compound Names A Roman numeral in parentheses, followed by the name of the element, is used for elements that can form more than one positive ion. � ______________________ 16. Certain elements assume the same oxidation number in different compounds; fluorine, for example, has the oxidation number −1 in all its compounds. Naming monatomic ions and ionic compounds. Dalton's atomic theory. � NH41+ NO21- 19. ______________________ 14. � Edit. K1+ C2H3O21- 20. Oxidation Number Chart Chemical Species Examples Oxidation Number All atoms in ELEMENTS (monatomic and diatomic) Mn (s), O 29g), Fe (s) 0 IONIC COMPOUNDS Alkali (Group 1) Na, Li, K, Rb, Fr Halogens F, Br, I Na cl, K 2 SO 4 Ba F 2, NH 4 Br +1-1 HYDROGEN in NH41+ P3- 6. ______________________ 19. For water, oxygen has a oxidation number while hydrogen has a. 1. � Oxidation Numbers Each Sodium atom gives up 1 electron, so 2 Sodium atoms (Na 2) will give up 2 electrons and have a charge of 2+. 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 ). This is because the metals in the glaze are oxidized, and this chemical reaction causes the met… Li1+ CO32- 10. <>>> � � Mg2+ 2 NO31- 18. 2 Na1+ Cr2O72- ( 1 N [ � � � � � � � % ' S U \ ] _ � � � � � � � � � � � � � � ( * 1 2 4 ] _ f g i � � � � � � � � � � � � � � � � � 2 3 ` a b c e f � � � � � � � � � � # $ % � � � �� CJ H*OJ QJ CJ H*OJ QJ 6�CJ OJ QJ 6�CJ OJ QJ 5�CJ V ( N O � � � � � L M � � � � � � !

Losing 1 electron Gaining 1 electron An ionic bond The Symbols Ionic Compounds Mg 2+ F1-The number of electron arrows comes from the oxidation numbers. Li1+ CO32- 10. 0 0. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.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. �� l ( � i 4 @�� 4 N o r m a l CJ _HmH sH tH 8 @ 8 H e a d i n g 1 $@&. ______________________ 4. ______________________ 7. <> Save. Write the formulas for the four ionic compounds that can be made by combining the cations Mg2+ and Fes+2.43 (a) (NH 4) 2 CO 3 (d) AlPO 4 (b) CaI 2 (e) AgCH 3 CO 2 1. � CuF2 14. Such numbers are written to the _____ of the symbol for the element. R � � � The more electronegative atom is assumed to take the bonding electrons, so its oxidation number will be negative - it mimics an anion. What is the charge for an ion in group 1? � In the case of an ionic compound, oxidation numbers are assigned based on the number of electrons transferred between reacting species. X � are one-atom ions Oxidation numbers: + or –number � ______________________ 17. ______________________ 5. What is the charge for an ion in group 1?
