Oxidation states (oxidation numbers) Oxidation states simplify the process of determining what is being oxidized and what is being reduced in redox reactions. Unless you have hydrides or peroxides (not the case here), give H a +1 and O a -2 for oxidation numbers. All Rights Reserved. In almost all cases, oxygen atoms have oxidation numbers of -2. There are a few exceptions to this rule: When oxygen is in its elemental state (O 2), its oxidation number is 0, as is the case for all elemental atoms. Its symbol is Ne and atomic number is 10. Oxidation number of Group 1 element in compound is +1. Its symbol is Ne and atomic number is 10. The group of C (group 14) has 4 electrons i n the last cap, they tend to share them, have oxidation number +4 with the nonmetals, and oxidation number – 4 with the metals and H. The pnictogens (group 15, or group of N) has 5 electrons i n the last cap, they tend to earn 3, having always with H and with the metals oxidation number – 3. However, N can change it's oxidation number from -3 to +6. The oxidation number of Neon is 0.
