Iron 55 (Fe-55). Iron has 28 known isotopes, with mass number between 45 to 42 ), 4 stable (Fe-54, Fe-56, Fe-57 and Fe-58) and 4 radioactive (Fe-52, Fe-56, Fe- The atomic mass of an element is the total number of protons and neutrons in the nucleus of Lithium Li, 3____________ Bromine Br, 35___________ Iron Fe, Aug 2, 2012 How many protons, neutrons, and electrons are present in each of the nuclides below? Iron (Fe): atomic number = 26, mass number = 56; Iodine- Jan 30, 2015 The team used accelerator mass spectrometry (AMS) – the same method Instead of using the 60Fe half-life, they compared the number of Mar 6, 2014 The atomic number of all the isotopes of iron is 26.

4. Neutral atoms of the same element can differ in"; a. chemical properties. (b) mass number. c. atomic number.

percent by mass = 111.70 g Fe / 159.70 g e 2 O 3 x 100 = 69.94% Fe in Fe 2 O 3 percent by mass = 167.55 g Fe / 231.55 g Fe 3 O 4 x 100 = 72.36% Fe in Fe 3 O 4 Hematite is 69.94% Fe, magnetite is 72.36% Fe. Magnetite contains a greater percentage of iron per kilogram than As an example, 56 Fe + n 0 57 Fe. 56 Fe and 57 Fe are two different isotopes of iron. They have different nuclear masses, but have the same nuclear charge (same number of protons) and essentially identical chemical reactivity. Number of moles of Fe = Given mass of Fe / Molecular mass of Fe. Number of moles of Fe = 7.85 g / 56 g = 0.1402. Ans: Number of moles of Fe = 0.1402.
