... An atom and its parts are much smaller than a meter. The diameter of an atom is 10-10 (0.0000000001) meter, whereas an electron is smaller than 10-18 (0.000000000000000001) meter. Comparatively, this means that an electron is 10 million times smaller than an atom! Most of the atom is empty space! Yo ...
