Where is the proton number on an element?

The atomic number (represented by the letter Z) of an element is the number of protons in the nucleus of each atom of that element.

Where is the number of protons and neutrons?

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
