Unformatted text preview: Fe + O 2 Fe 2 O 3 3. The volume of an atom is primarily defined by electrons. Calculate the density of the electrons for the ion, 7 Li + in g/cm 3 given that the mass of an electron is 9.1×10-28 g, and the radius ( r ) of the atom is 9.0×10-9 cm. Assume the ion is a sphere, and the volume of a sphere is: ( π = 3.14) 3 3 4 r V π =...
