1 caf 2 calcium fluoride 1 if all of the atoms in a crystal are the same size then there are two ways to pack the atoms to form a crystal structure.
Within a given shell all of the subshells are close to each other in energy but not exactly the same. Bohr assumed that an electron of an atom is located at a definite distance from the nucleus and revolves around the nucleus with a definite velocity ie the momentum of the electron is fixed which is against heisenbergs uncertainty principle. Lower energy subshells fill before higher energy subshells. A strong understanding of ions is needed.
