I wanted to do... so that's Calcium instead I wanted to write the electron configuration for iron which is in the D block so turns out and this is kind of an artifact and I'll do a more detailed video on this in the future that it actually goes and backfills the 3rd energy shell because all of the sudden the D orbitals can kind of fit in the gaps of the 3rd energy shell so what you do is you go one energy shell above it
