The equilibrium number of vacancies in 1 cm3 of pure molybdenum at a certain temperature is 3340. If there are 6.40 × 1028 atomic sites in 1 m3 molybdenum at this temperature and its activation energy for vacancy formation is 3.34 eV/atom, calculate the temperature in degrees Celsius.

Which of the following observations indicates that there is a small, dense, positively charged part in the center of an atom? some uncharged particles are scattered by a gold foil. all uncharged particles are attracted towards a gold foil. all positively charged particles pass straight through a gold foil. some positively charged particles bounce back from a gold foil.
