    Atomic number of iron = 26

    Number of protons in the neucleus = 26

    Number of electrons in a neutral Fe atom = 26

    Number of electrons in Fe2 + ion = 26 - 2 = 24

    The answer is (1) 24. There are 26 protons in nucleus of Fe atom. There is 26 electrons in Fe atom. Fe atom loses 2 electrons and change to Fe2 + ion. So there is 24 electrons in Fe2 + ion.
