Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Understand the Chemical Name Components
The name Fe$$_{2}$$O$$_{3}$$ contains two key pieces of information:
- The chemical symbol Fe represents iron - The subscript 2 indicates two iron atoms - O represents oxygen - The subscript 3 indicates three oxygen atoms
Step 3:: Determine the Iron's Oxidation State
In this compound, iron has a + 3 oxidation state (III), which means each iron atom has lost 3 electrons.
Step 4:: Explain the Roman Numeral Notation
- This is different from iron (II) oxide (Fe$$_{2}$$O), which would have a +2 oxidation state
The Roman numeral (III) in iron (III) oxide indicates the specific oxidation state of iron:
Step 5:: Verify the Charge Balance
- Charge balance: $$2 \times (3^{+}) = 3 \times (2^{-})$$, which confirms the correct ionic composition
- Oxygen ion: O^{2 -}
Final Answer
Fe_{2}O_{3} is named iron (III) oxide because it contains iron ions with a + 3 oxidation state, which is represented by the Roman numeral III in its systematic name.
