2. The approximate radius of a nucleus, r, is given by the formula r = A$(1.3x10-13cm), where A is the mass number of the nucleus. What is the radius of the Al nucleus in decimeter. The atomic radius of the Al is approximately 143 pm. If the diameter of this atom were 1.00 km what would be the diameter of its nucleus (in ft)? Calculate also the percentage of the total volume of the aluminum atom that is occupied by the nucleus. A) 3.9x1014, 0.088, 3.0x10-6 B) 3.9x1014, 0.088, 2.0x10-8 C) 3.9x1014, 0.068, 2.0x10-6 D) 3.9x1014, 0.088, 2.0x10-6 E) none of the above
