To find the number of valence electrons for Fe (Iron) we need to look at its electron configuration. The valence electrons can vary from -2 to +6, but the most common valence electron listings are +2 and +3. Since the 3s if now full we'll move to the 3p where we'll place the next six electrons. This is tricky! I want the answer for the neutral atom of iron without any oxidation or anything. The atomic number or iron is 26, and it has 26 electrons and 26 protons. Metallic bonding a property in many other transition metals because the large number of electrons in the third energy level shield the positive nucleus from the two outer valence electrons. Elements in groups 15, 16 or 17 tend to gain electrons to become anions. So the full electron configuration is 1S2, 2S2, 2P6, and 3S1.
