Questions & Step-by-Step Solutions

What is the electron configuration of the ion Fe3+?
  • Step 1: Identify the atomic number of iron (Fe), which is 26.
  • Step 2: Write the electron configuration for a neutral iron atom (Fe). It is 1s2 2s2 2p6 3s2 3p6 4s2 3d6.
  • Step 3: Determine that Fe3+ means the iron atom has lost 3 electrons.
  • Step 4: Remove 2 electrons from the 4s subshell and 1 electron from the 3d subshell.
  • Step 5: The remaining electrons after losing 3 are: 1s2 2s2 2p6 3s2 3p6 3d5.
  • Step 6: Write the simplified electron configuration using the nearest noble gas (argon, Ar) as a reference: [Ar] 3d5.
