0 in the elemental form, +3 in its compounds
The oxidation number of Al is +3.

Yes. It is true. An atom with a different atomic number is an atom of a different element.

+3 for Al, -1 for each F
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
The oxidation number of Al is +3.
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 of Al is +III and S is -II.
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.
