  One atom of carbon weighs 0.00000000000000000000019942 grams – so not many! One of my friends from uni does computational physics, and someone in her lab took this photo of a single atom. You can only see it because it’s fluorescing (glowing) though https://epsrc.ukri.org/newsevents/news/single-trapped-atom-captures-science-photography-competitions-top-prize/
