Compare the structure of silicon oxide and diamond and describe their physically properties in terms of these structure

Here's what I get  

Explanation:

Both diamond and SiO₂ are network solids. Their atoms are all joined together so a crystal of either diamond or SO₂is one giant molecule.

Structure

In diamond, each C atom is covalently attached to four other C atoms.  

The structure of SiO₂ is like that of diamond. The difference is that there is an O atom between each atom of Si.

Properties

Both substances are

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
