Question

An example of a network solid is?

• A. limestone, $Ca{CO}_3$
• B. table salt, $NaCl$
• C. diamond, $C$
• D. dry ice, ${CO}_2$
• E. iodine, $I_2$

Answer 1

The correct option is C diamond, $C$

$\begin{array}{c}\text{Network solid is a type of solid in which the constituent atoms}\\ \text{are held together strongly by a regular parttern of covalent}\\ \text{bonds or its network on atoms.}\\ \text{Examples}\to C\left(\text{diamond}\right),\mathrm{SiC}\text{,}AlN\text{etc.}\\ \text{while, limestone}\left(CaC{O}_3\right)\text{and table salt (NaCl) are ionic solids.}\\ \text{Dry ice (solid}\left(C{O}_2\right))\text{and}{I}_2\left(g\right)\text{are molecular solids.}\end{array}$
