Because all the ohers are bigger!
A single atom of hydrogen-1 is the smallest particle of hydrogen. A hydrogen-1 atom contains only one proton and one electron, and is the simplest atom.
Smallest atom is hydrogen Largest atom is Francium
the atom with the least mass is the hydrogen atom
Well obviously Hydrogen is the smallest atom because it only has one electron, this makes it unstable, but aside from that the period is 1.
Because it only has one electron for the nucleus to attract.
The smallest atom is hydrogen.
yes the smallest atom is hydrogen
The smallest atom is hydrogen.

hydrogen This is because it has the smallest Relative Atomic Mass =]
A hydrogen atom has the smallest radii.
The smallest atom is the atom oh hydrogen.
