The diameter of a mercury atom, atomic number 80, compared with the diameter of a zirconium atom, atomic number 40, is approximately
1) half as large 2) twice as large 3) the same size because the 4) atomic masses are not appreciably different. 5) greater nuclear charge pulls the orbiting electrons closer. 6) atomic number and atomic diameter are directly proportional to each other. 7) atomic number and atomic diameter are inversely proportional to each other.
