Question

$MgO$ has $NaCl$ type structure and $TiCl$ has $CsCl$ type structure of ions in each ($MgO$ and $TiCl$)?

Answer 1

$MgO$ has $NaCl$ type of structure.

$\therefore$ Co-ordination number of ions in $MgO=6$

[$NaCl\to fcc\to 6$]

Co-ordination number of ions in $TICl=8$

[$CsCl\to bcc\to 8$]
