On the periodic table, this number is found above the element symbol. Name: Iron Symbol: Fe Atomic Number: 26 Atomic Mass: 55.845 amu Melting Point: 1535.0 °C (1808.15 K, 2795.0 °F) Boiling Point: 2750.0 °C (3023.15 K, 4982.0 °F) Number of Protons/Electrons: 26 Number of Neutrons: 30 Classification: Transition Metal Crystal Structure: Cubic Density @ 293 K: 7.86 g/cm 3 Color: Silvery Atomic Structure Mass Number. Iron-56 is the most common isotope of iron. ... For iron, the symbol is Fe and the atomic number is 26. Neutrons 30 . The mass of the atom is a unit called the atomic mass unit $$\left( \text{amu} \right)$$. Protons 26 . Thus, the isotope Fe-56 has 26 protons, 30 neutrons, and 26 electrons. The iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Subsequently, question is, how many electrons protons and neutrons are there in an atom of iron 56? Iron was discovered by humans before 5000 BC. Nuclide Data . Iron has an atomic weight of 55.845g/mol. Atomic Number of Iron. The number of protons makes each element unique, so they are organized by these numbers on the periodic table. See more Iron products. The mass number ($$A$$) of an atom is the total number of protons and neutrons in its nucleus. (If the protons don't match the electrons, the atom is ionized, not neutral as usually assumed. Get an answer for 'give the symbol and number of protons in one atom of:Lithium__ Iron __ Oxygen __ Krypton_ Bromine _ Copper __ Mercury__ Helium __ … Binding energy 492253.892 ± 1.356 keV . 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.
