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.

Element 95 is americium.
An electric charge in our atmosphere which hurtles towards earth through the aid of moisture in the air during a storm. It is always followed by thunder (which is th delayed sound of the lightning crackleing)
Uranium
Copper has 1+ charge, but there is Cu2+ ---> copper (II).
Thorium was discovered by Jons Jakob Berzelius in 1828.
Th is element number 90 on the periodic table It is thorium, it is in the Actinides, and it is radioactive
