Question

each atom is assigned an oxidation number in a chemical species irrespective of the overall charge of that species

Explanation:

Oxidation numbers are assigned to each atom in a chemical species. The sum of oxidation numbers of all atoms in a species equals the overall charge of the species. For example, in a neutral molecule like \(H_2O\), the sum of oxidation numbers of \(H\) (each \(H\) is \(+ 1\)) and \(O\) (\(-2\)) is \(2\times(+1)+(-2)=0\). In an ion like \(SO_4^{2 -}\), the sum of oxidation numbers of \(S\) (let its oxidation number be \(x\)) and \(O\) (each \(O\) is \(-2\)) is \(x + 4\times(-2)=-2\), so \(x = +6\). So, oxidation numbers are assigned considering the overall charge of the species.

Answer:

False
