WebNov 21, 2024 · Iron is a chemical element with atomic number 26 which means there are 26 protons and 26 electrons in the atomic structure. The chemical symbol for Iron is Fe. … WebFor example: iron-56 has 30 neutrons and 26 protons, an n:p ratio of 1.15, whereas the stable nuclide lead-207 has 125 neutrons and 82 protons, an n:p ratio equal to 1.52. This is because larger nuclei have more proton-proton repulsions, and require larger numbers of neutrons to provide compensating strong forces to overcome these electrostatic ... import a text file python
