To do this we trap 87Rb atoms in a cigar-shaped, high frequency magnetic trap created from an atom chip depicted below. We then cool the atoms to degeneracy and use a Sagnac interferometer geometry to ...

The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...
