WebWe know that the atomic number of iron is 26 and the atomic mass number is about 56 (55.84u). Neutron (n) = 56 – 26 = 30. Therefore, the number of neutrons in iron is 30. What are the valence electrons of iron? The 1st element in group-8 is iron and it is the d-block element. The elements in groups 3-12 are called transition elements. WebJun 8, 2024 · In the nickel nucleus represented above, the atomic number 28 indicates that the nucleus contains 28 protons, and therefore, it must contain 31 neutrons in order to have a mass number of 59. The uranium nucleus has 92 protons, as all uranium nuclei do; and this particular uranium nucleus has 146 neutrons.
