KBr crystallizes in a face-centered lattice. The ionic radii of K+ and Br– ions are 133 pm and 195 pm, respectively. Calculate the density and Packing efficiency for KBrl?
Place the following salts in order of increasing lattice energy. NaCl, KBr, BeO I really need help with this. I know that ionic charge and size matters with lattice energy, but I am confused with comparing size. There are two ion in one molecule! which one should I compare?
