Answer:
26 protons
30 neutrons
Step-by-step explanation:
Fe is element 26, so it has 26 protons, with a +1 charge on each.
The atom of iron shown here has an atomic mass of 56. Since there are 26 protons, and electrons have a very small mass, the number of neutrons (1 amu each) is (56-26) = 30 neutrons.
A neutral iron atom would have equal numbers of protons and electrons. This fellow is neutral, so it has 26 electrons.
