Seven years. And after that you get carbon dioxide (& water)

Source? Wikipedia says: "an estimated lifetime of 8.9±0.6 years in the atmosphere." Which suggests a half life of 1/2 that.

A half-life describes an asymptotic curve. You don't just divide a "lifetime" by 2.

1 + 1/2 + 1/4 + 1/8 + 1/16... = 2 so it's not that far off as an approximation but yea 1/LN(2) = 1.44 so the low number is 5 point something years and the high is 6 point something years.
