(a) Atoms are very small compared to objects on the macroscopic scale. The radius of a nickel atom is 125 pm. What is this value in meters and in centimeters? cm -23 (b) The mass of a single nickel atom is 9.75×10 g. Suppose enough Ni atoms were lined up like beads on a string to span a distance of 31.3 cm (12 inches). How many atoms would be required? atoms What mass in grams of Ni would be used? Could you weigh out this amount of nickel using a typical laboratory balance? (c) Taking the density of nickel metal to be 8.91 g/cm, calculate the mass of metal needed to form a piece of Ni wire with the same length as the distance in b, but with a diameter of 1.00 mm.
