Atomic Number of Iron. Thus, the isotope Fe-56 has 26 protons, 30 neutrons, and 26 electrons. Iron-56 [[Image:|250px|]] Full table . The number of protons makes each element unique, so they are organized by these numbers on the periodic table. Iron (atomic symbol: Fe, atomic number: 26) is a Block D, Group 8, Period 4 element with an atomic weight of 55.845. Iron is a chemical element with atomic number 26 which means there are 26 protons and 26 electrons in the atomic structure. Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. The number of protons that are found in an atom of an element is called the atomic number. Iron was discovered by humans before 5000 BC. The chemical symbol for Iron is Fe.. Atomic Mass of Iron. One atomic mass unit is the mass of a proton, or about \(1.67 \times 10^{-27}\) kilograms, which is an extremely small mass. Name: Iron Symbol: Fe Atomic Number: 26 Atomic Mass: 55.8 Number of Protons/Electrons: 26 Number of Neutrons: 30 Classification:Transition Metals Discovery: … The symbol for iron is Fe from the Latin word ferrum meaning iron. Iron has twenty-six protons, so its atomic number is 26. The iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. See more Iron products. The mass of the atom is a unit called the atomic mass unit \(\left( \text{amu} \right)\). Iron has an atomic weight of 55.845g/mol. Mass Number. Binding energy 492253.892 ± 1.356 keV . ... For iron, the symbol is Fe and the atomic number is 26. Natural abundance 91.754% . Protons 26 . Iron-56 is the most common isotope of iron. The mass number (\(A\)) of an atom is the total number of protons and neutrons in its nucleus. Isotope mass 55.9349375(7) u . Neutrons 30 . Name, symbol Iron-56, 56Fe . Since the iron has the atomic number z Fe = 26, we have 54 - 26 = 28 neutrons in 54 Fe, and 30, 31, and 32 neutrons, respectively, in the other three isotopes given. (If the protons don't match the electrons, the atom is ionized, not neutral as usually assumed. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance.
