The element oxygen has three naturally occurring isotopes, with 8,9, and 10 neutrons in the nucleus, respectively. (a) write the full chemical symbols for these three isotopes. (b) Describe the similarities and differences between the three kinds of atoms of oxygen.

(a) Atoms are very small compared to objects on the macroscopic scale. The radius of a vanadium atom is 131 pm. What is this value in meters and in centimeters? cm (b) The mass of a single vanadium atom is 8.46×10-23 g. Suppose enough V atoms were lined up like beads on a string to span a distance of 44.7 cm ( 18 atoms inches). How many atoms would be required? What mass in grams of V would be used? Could you weigh out this amount of vanadium using a typical laboratory balance? (c) Taking the density of vanadium metal to be 6.08 g/cm³, calculate the mass of metal needed to form a piece of V wire with the same length as the distance in b, but with a diameter of 1.00 mm. Hint: The volume of a cylinder is T times its radius squared times its height. (V = T r² h) How many vanadium atoms does this represent? atoms
