1. if styrofoam ball and a steel ball are the exact same size & shape: a. describe the volume (which has more, or are they the same):

Volume is the amount of space an object or substance takes up, so if they are the same size then they will have the same volume. If you wish to test this, get a beaker, fill it up to one of the lines and make sure tou remeber which line, then place one ball in gently and see how muchbit went up, then take that ball out and do the same with the other. The results should be the same.

Hope this helps!

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 -
