How can you use the periodic table to find the number of protons in one atom of an element?

The number of protons is the same as the atomic number of the element.

The number of protons is the same as the atomic weight of the element.

The number of protons can be found by subtracting the number of electrons from the number of neutrons.

The number of protons cannot be determined from the information on the periodic table.
