    The biggest naturally-occuring atom is Uranium. The largest measurement I can find for the diameter of a Uranium atom is 392 picometers. 1 Angstrom = 100 picometers. So 392 picometers = 3.92 Angstroms for the "size" of the biggest atom. The smallest molecule is the hydrogen molecule (2 hydrogen atoms bonded together), which is about 1.48 Angstroms in diameter. So, if my research is correct, the "smallest" molecule is less than half the size of the "biggest" naturally-occurring atom. I hope someone will correct this info if it's wrong.
