(a) (b) Draw the arrangement of atoms on the face of a BCC unit cell of lattice constant 2 Å. Determine the closest distance between neighbouring atoms in units of cm. Find the packing fraction of the BCC unit cell and state any assumptions you've made in your calculations. 11.2 The energy levels of an atom X are given by E₁ = -1² eV where n is the principal quantum number. If a photon of wavelength 5.893 × 10-7 m is emitted from the atom, explain with calculations how this is possible. Determine the energy (in Joules) required to ionize the atom.
