Very much depends upon the element you are talking about. Each are different, and each varies in size a million times a milli-second. In fact, some change so fast, they defy the laws of physics as we know them, because electorns can appear in two places around the nucleus at the exact same time

Atoms are genearally on the order of 10e-8 cm wide (or 0.1 nm). That means you could put 100 million atoms side by side to get to one centimeter in length. The hydrogen atom is the smallest, and the size increases as you go up the periodic table. Say, maybe up to 0.5 nm.

It depends on the atom. The yardstick for measuring atoms is the Bohr radius, which is about half an angstrom. (5x10^-11 meters). The yardstick for measuring the nucleus is the fermi, which is 10^-15 meters, much smaller.

it varies from element to element. check a periodic table, for mass and diameter of each element's atoms
