The unit cells for cesium chloride and barium(II) chloride are shown here. Show that the ratio of cations to anions in each unit cell corresponds to the ratio of cations to anions in the formula of each compound. -ar Cs ar Ba+ Cesium chloride Barium chloride

How many atoms of barium are in the unit cell? what type of cubic cell is this (face-centered, simple cubic, or body-centered)? What is the radius of the barium atom? the textbook provides the values

In an experiment, you measure the proportion of unit cells that occupied by atoms. For one cell, you measure 52% of the cell i occupied by atoms (with 48% empty space), for another cell, y measure 68% is occupied by atoms (with 32% empty space) ar for a 3rd cell you measure 74% is occupied by atoms and 26% i empty space. Which one of these should be the face-centered cubic arrangement? is ½ of a sphere. There are 6 faces, so this gives a total each 2 edge 52% occupied by atoms 74% occupied by atoms & C. Cell type 68% occupied by atoms none are true Num

Part A The unit cells for lithium oxide and silver iodide are shown below (Figure 1). Show that the ratio of cations to anions in the unit cell of Li,0 corresponds to the ratio of cations to anions in the formula of the compound. Match the numbers in the left column to the appropriate blanks in the sentences on the right. Reset Help 1 The Li atoms occupy position(s) inside the unit cell, giving 2 Li atom(s)/unit cell. 3 Figure < 1 of 1 The O atoms occupy corner 4 position(s) and face-center 5. position(s) of the unit cell, giving O atom(s)/unit cell. The ratio of Li :0 atoms is 8 which reduces to 10
