For an uncombined atom, the oxidation number is 0. It does not give away any electrons. It does not accept electrons from anywhere either.
Zero.
0- any element by itself has an oxidation number of 0.
The oxidation number of an atom describes the number of electrons that an element has partially/entirely accepted/donated. A neutral atom has oxidation number of 0. When forming an ion, the overall oxidation number is equivalent to its charge.
It is the square root of a piece of cheese after I bit it off and eaten a cracker.
If an atom loses electron, then it will have a positive oxidation number. If an atom gains electron, then it will have a negative oxidation number.
Zero.

The oxidation number of an atom describes the number of electrons that an element has partially/entirely accepted/donated. A neutral atom has oxidation number of 0. When forming an ion, the overall oxidation number is equivalent to its charge.

If an atom loses electron, then it will have a positive oxidation number. If an atom gains electron, then it will have a negative oxidation number.
Oxidation number increases when the atom is oxidised, and decreases when it is reduced
Oxidation state is what determines the number of each atom. This is in the ionic formula.
Each Br atom has an oxidation number of zero.
Oxidation is a chemial reaction; the atom and the number of neutrons remains unchanged.
Pottasium has +1 oxidation number.Iodine has -1 oxidation number.
The oxidation number implies that how many electrons that a particular element has partially/fully accepted/donated. The oxidation number for any neutral atom is 0. The oxidation number of an atom is equal to its overall charge.
Each Br atom has an oxidation number of zero.
