It depends, if the atom needs to stay happy (balance) then 2. If it needs one to stay balanced then it will have 1. So I guess you can say 1.
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
A neutral atom must contain an equal number of electrons because it is a neutral atom.
the smallest atom is hydrogen, the smallest molecule would be the naturally occurring diatomic hydrogen.
The element with one proton per atom is hydrogen.
The smallest quantity of an element is an 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.
An atoms size is relative to the number of electrons an atom contains. Atoms with the least number of electrons are the smallest atoms. When atoms have the same number of electrons, the atom with the most protons will have the largest nuclear charge, and therefore be the smallest atom.

The atom, which contain protons, neutrons and electrons; the protons and neutrons contain quarks and gluons.
The smallest atom is hydrogen.
The element with one proton per atom is hydrogen.
Atom is the smallest paricle for matters. Nucleus of it is posistioned at the center and it contains protons and neutrons. LaDy_caRoLi "christine carren alcantara"

The smallest quantity of an element is an atom.
The neutral iodine atom contain the same number of electrons as protons - 53.
