    The video is very useful for few last days before the exam and congratulations on effort! One small mistake is at 30:00, the atomic radius increases down the group and decreases across the period.

    Correct me if I’m wrong, but I thought at 16:25 The Subshell Order of Filling is meant to be: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p...?

      ​@Tanush ! That is not the issue at all. When writing the electron config, you can write it either way around, and yes, it is preferred to write the 3d before the 4s.
      Surprisingly, the issue isn't that she said 3d before 4s.
      No, the issue is somehow worse, and very clear if you just click the timestamp in the comment - she specifically states that "the order of filling therefore is 1s, 2s, 2p, 3s, 4s, 3p, 4p, 4d." She doesn't even say 3d.
      I've compiled a playlist of chemistry revision and haven't watched this video yet, but going by the comments and the sheer amount of errors, I think I'll be removing this one from the playlist. If only we had a way to show others with a simple counter that a video is bad, like a dislike button, _UA-cam_
