Question: The interatomic \"spring\" (chemical bond) between atoms in a block of aluminium to be 16 N/m. Since in our model each atom is connected to two springs, each half the length of the interatomic bond, the effective \"interatomic spring stiffness\" for an oscillator is 4*16 N/m = 64 N/m. The mass of one mole of aluminium is 27 grams (0.027 kilograms). Find the energy, in joules, of one quantum of energy for an atomic oscillator in a block of aluminium?
