This is full of mistakes! He uses full arrows to represent one electron rather than half arrows. Then he quotes the electron structure of one element with the wrong orbital numbers, then he does chromium wrong, forgetting that the 4s electron gets promoted, so it should be 4s1 3d5 ! Utterly useless! Made a good laugh when I showed this to my chemistry class though!
