A hydrogen atom has the smallest diameter because there is only one proton and neutron.
ATOM
Br is the atom with the smallest. K+ is the ion with the smallest radius. In general, the shape with the smallest radius has the smallest diameter
The smallest atom is helium (nucleus and electrons) while francium is the largest. Helium: 28 picometer francium: 260 picometer
The smallest atom is hydrogen.
The atom that is smallest in size is the hydrogen atom.
Sandia National Laboratories have created "nanogears" which are 1 atom thick and only a couple of nanometers in diameter.
yes the smallest atom is hydrogen
The smallest atom is hydrogen.
The smallest quantity of an element is an atom.
Sandia National Laboratories have created "nanogears". Which are one atom thick and only a couple of nanometers in diameter.
Smallest atom is hydrogen Largest atom is Francium
The diameter of a helium atom is approximately 0.1 nanometers, or 1 angstrom. In meters, this translates to about 1 × 10^-10 meters. Helium atoms are among the smallest atoms, with their size largely determined by the electron cloud surrounding the nucleus.
