  • Group 12 elements are classified as TM
  • AM color lightened
  • Categories removed (name or class): Unknown, Post-Transisiton metal, Reactive nonmetal.

Issues[edit]

  • No categories except ONONM, HAL, & NG meet AAA
  • AM and AN do not meet AA
  • PTM/MOID are too similar
  • SoM should have other distinguishers in addition to, or instead of, color.
