The number of network solids and ionic solids in the list given below is respectively H 2 O ( ice ) , AlN , Cu , CaF 2 , diamond , MgO , CCl 4 , ZnS , Ag , NaCl , SiO 2

Step-by-step solution

A wide variety of crystalline solids of non-metals result from the formation of covalent bonds between adjacent atoms throughout the crystal. They are also called giant molecules. Covalent bonds are strong and directional in nature, therefore atoms are held very strongly at their positions.   AlN ,   diamond ,   SiO 2 are covalent or network solids Ions are the constituent particles of ionic solids. Such solids are formed by the three dimensional arrangements of cations and anions bound by strong cou
