The correct Answer is:
To determine the net charge on the ferrous ion, we can follow these steps: ### Step 1: Identify the Element The ferrous ion is derived from iron, which has the chemical symbol Fe. ### Step 2: Determine the Atomic Number Iron has an atomic number of 26. This means it has 26 protons in its nucleus. ### Step 3: Understand the Electron Configuration The electron configuration of iron is: - 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁶ 4s² ### Step 4: Formation of the Ferrous Ion The ferrous ion (Fe²⁺) is formed when iron loses two electrons. This typically occurs from the outermost shell, which includes the 4s and 3d orbitals. When iron loses two electrons, it becomes: - Fe → Fe²⁺ + 2e⁻ ### Step 5: Determine the Charge of the Ferrous Ion Since the ferrous ion has lost two electrons, which are negatively charged, the net charge on the ferrous ion is: - Charge = Number of protons - Number of electrons - Charge = 26 protons - (26 - 2) electrons = 2 Thus, the net charge on the ferrous ion is **+2**. ### Final Answer The net charge on the ferrous ion (Fe²⁺) is **+2**. ---
