What is the result of this oxidation?
When a substance is oxidized, it loses electrons. Thus, its oxidation state becomes more positive.
Which group has more than one positive oxidation state?
The transition metals (groups 3-12) can have more than one positive oxidation state. When you write the names of compounds with transition metals, you note their oxidation state with roman numerals, e.g. iron (II) oxide and iron (III) oxide.
How is oxidation number different from valence electrons?
Valence is how many bonds an atom can form. Oxidation number can be though of as being similar to the charge on an ion, and is based on the difference in electronegativity between bonded atoms. If something is bonded to a more electronegative element, its oxidation state is positive, and if it is with a less electronegative on the state is positive. In a neutral substance the sum of the oxidation states is always zero. Valence and oxidation states are related, though.Example: In formaldehyde (CH2O) hydrogen has a valence of 1, oxygen a valence of 2, and carbon a valence of 4. Carbon is more electronegative than hydrogen, and less electronegative than oxygen. As a result, each hydrogen atom has an oxidation state of 1+ and the oxygen is in the 2- oxidation state. This puts carbon in an oxidation state of 0.
What happens to atoms in an oxidation-reduction reaction?
The oxidation state of one atom increases while another decreases.
When is the oxidation state of a metal indicated in the name of a compound?
When the metal can exist in more than one oxidation state

What is the most common oxidation number for group three on the periodic table?
Generally third A group elements in the periodic table exhibit +3 oxidation state but Boron exhibit negative oxidation state also . The stable oxidation state of Tl is +1. It exhibit +3 also but +1 is more stable than +3. RGUKT IIIT NUZVID N091528

The oxidation state of one atom increases while another decreases.
When is the oxidation state of a metal indicated in the name of a compound?
When the metal can exist in more than one oxidation state
What is more likely oxidation state of Chlorine?
The most common oxidation state for chlorine is 1- (negative one).
What is the oxidation state of zinc in diethylzinc?
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
When is the oxidation state or a mental indicated in the game of compound?
When the metal can exist in more than one oxidation state (apex)
Why is the oxidation state of fluorine never positive?
An element exhibits a positive oxidation state when it is bonded to a more electronegative element. Fluorine is the most electronegative of all the elements. But what if fluorine bonds with extremely elecronegative oxygen and nitrogen ligands like -OCF3, -OTeF5, -OIO2F2, -N(SO2CF3)2, -N3, -N5(pentazole ligand) etc.? eg: F-OTeF5
What is a reaction that removes one or more electrons from a substance such that the substance's valence or oxidation state increases?
