Electron Configurations

Iron has 26 electrons so its normal electron configuration would be: Fe 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 6. When we make a 3 ion for Iron, we need to take the electrons from the outermost shell first so that would be the 4s shell NOT the 3d shell: Fe 3 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5. One other note on writing electron configurations: A short cut.

Give reasons for the following: i Fe has higher melting point than Cu. ii Ti H2O 6 3 is coloured while Sc H2O 6 3 is colourless. Ans. i This is because Fe 3d6 4s2 has four unpaired electrons in 3dsubshell. While Cu 3d10 , 4s1 only one unpaired electron in 4s shell. Hence metallic bonding is stronger in Fe than those in Cu.
