There are 102 elements named in the song lyrics, in a totally disorderly order. The date of the song (1960-ish) gives a clue to which elements. For a long time around then there were just 102 recognised elements, all atomic numbers up to 102, and 103 and beyond were in process of discovery and recognition. So the elements that were not included were those artificial elements that had not yet been recognised: elements 103-114 and 116.
