what is the electronic configuration for Iron. Write out the orbital box diagram and the condensed electron configuration (not the Nobel Gas electron configuration) for Iron

1 answer

The atomic number of iron is 26, which means it has 26 electrons.

The orbital box diagram for iron is as follows:

1s: █ █ █ █
2s: █ █
2p: █ █ █
3s: █ █
3p: █ █ █ █ █ █
3d: █ █ █

Condensed electron configuration for iron: [Ar] 3d6 4s2
