Directions: count the number of atoms. ar co2 na3po4 so3 nac2h3o2

We have:
1 atom of Ar
2 atoms of O and 1 atom of C (3 atoms)
3 atoms of Na,1 atom of P and 4 atoms of O (8 atoms)
1 atom of S and 3 atoms of O (4 atoms)
1 atom of Na,2 atoms of C,3 atoms of H,2 atoms of O(8 atoms)

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 -
