Assign an oxidation number to each elementary in the following compounds or ions n2o5

Oxidation number per Nitrogen +5, oxidation number per Oxygen -2

Explanation:

So we know that oxidation number of Oxygen is -2 so we have -2x5= -10 charge. This gives a total oxidation number charge of -10 for the five oxygen atoms in N2O5. To maintain electrical neutrality, as required for all compounds, the two nitrogen atoms must have a total oxidation charge of +10, so that each of the two nitrogen atoms has an oxidation number of +5

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

it's c. elements are placed in rows based on how may valencies electrons have.
