CaS exists in a cubic close packed arrangement of \( \mathrm{S}^{2-} \) ions in which \( \mathrm{Ca}^{2+} \) ions occupy \( 1 / 2 \) of the available tetrahedral holes. How many \( \mathrm{Ca}^{2+} \) and \( \mathrm{S}^{2-} \) ions are contained in the unit cell?https://bit.ly/YTAI_PWAP https://www.pw.live
