NO2 has a charge of negative 1.
The oxidation number of N in NO2 is +4. This is because oxygen has an oxidation number of -2, and there are two oxygen atoms in NO2, which gives a total charge of -4. Therefore, the nitrogen atom must have an oxidation number of +4 to balance the charges and make the overall compound neutral.
The chemical symbol of thorium is Th.
Thorium (Th) has 90 protons.
The charge of an electron is .16 E-18 Coulombs.
neutron
