NettetA typical atom is anywhere from 0.1 to 0.5 nanometers in diameter. DNA molecules are about 2.5 nanometers wide. ... How Small Are Atoms? It’s hard to imagine how small atoms are. One single atom is about one 250-millionth of an inch (0.000000004 inches). That’s the same as one ten-millionth of a millimeter across ... NettetThe number of electrons in the outermost shell determines how an atom will interact with other atoms, leading to chemical reactions and the formation of molecules. Atoms are incredibly small, with a diameter of about 0.1 to 0.5 nanometers. To put that in perspective, a human hair is about 100,000 nanometers thick.
