What is the smallest element in the universe?
HydrogenThey are the simplest and smallest Elements – Hydrogen and Helium. A Hydrogen atom contains one Proton and zero Neutrons. When two of these join together, one of them turns into a Neutron and makes a different kind of Hydrogen (called 2H, because it has 2 particles in the atom).
