A position versus time graph is shown: A Position versus Time graph is shown with y-axis labeled position in centimeters up to 15 and x-axis labeled time in seconds up to 10. A straight line connects the points 0, 0 and 3, 3. A horizontal line connects points 3, 3 and 6, 3. A straight line connects 6, 3 and 10, 11.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
