Answer Wiki. It turns out that sulfur hexafluoride, SF6, is the most potent greenhouse gas ever measured. Greenhouse gas potency is measured with an unit called the GWP or global warming potential, and it takes in account the molecule's ability to absorb infrared radiation and survival in the atmosphere. SF6 is an octahedral molecule, with six S-F bonds, each capable of absorbing infrared radiation very well.
Plutonium is the most dangerous element you can handle because it is highly radioactive. Just inhaling a small amount of plutonium dust will give you lung cancer. However, plu â¦ tonium is rather hard to come by so the most dangerous element you will probably come into contact with is mercury.
