82, the same as the atomic number.
The proton number is the atomic number.
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
The neutron-proton ratio for the nucleus of lead-206 ((^{206}_{82}\text{Pb})) can be calculated by determining the number of neutrons and protons. Lead-206 has 82 protons (as indicated by the atomic number) and 124 neutrons (calculated as 206 - 82). Thus, the neutron-proton ratio is 124 neutrons to 82 protons, which simplifies to approximately 1.51.
iron has 26 protons
We don't use a atomic number for a proton. But atomic number is the number of protons an atom contains.
1 / mass of a proton = avogadro's number 1 / mass of a proton = avogadro's number

The atomic number is equivalent to its number of protons. One proton in atom is its atomic number is 1. Hydrogen is the only atom with one proton.
The proton number is also known as the atomic number when referring to the periodic table. It represents the number of protons in the nucleus of an atom, which determines its chemical properties and its unique place on the periodic table.
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.
