Pull out your magnifying glass, now let's look down at the atoms. [action] Let's shrink down further...Here I have an atom in my hand. How small is the nucleus?

Atoms come in all different shapes and sizes. We do know how small an atom is but we aren't sure exactly what the diameter that the diameter of an atom is .1 to .5 nanometers.

Like bakers measuring the exact same amount of flour every time they made bread, physicists at The University of Texas at Austin have used a laser trap to consistently capture and measure the same ...

What are the biggest and smallest atoms? ... However, for very massive atoms, the force holding them together becomes unstable and they tend to break apart (a phenomenon known as radioactive decay).

The sample was cooled to less than 100 kelvin (-170 degrees Celsius) to reduce the vibrations of its atoms. ... For instance, a small vibration, even a sound, could smash the tip and the sample

Quantum chemical B3LYP/cc-pvqz computation of ground-state structures and properties of small molecules with atoms of Z £ 18 (hydrogen to argon) (IUPAC Technical Report)

The cooperative spontaneous emission by a fully inverted array of N atoms, interacting with and via the radiation field is studied.
