does this sound right?
In terms of its crystal structure, explain why diamond can scratch all other materials?
Diamond can scratch all other materials because the shape the diamonds carbon atoms make, makes it very strong. It's a very strong 3d shape, each carbon atom having 4 joined to it with covalent bonds. Due to diamond's great hardness and strong molecular bonding, a cut diamonds facets and facets edges are observably flattest and sharpest
Not bad.
The carbon atoms in diamond are covalently bonded and are very closely packed; we say that the *lattice density* is high.
This makes the crystal very hard so it can scratch other materials, but you should also know that "hard" doesn't mean unbreakable - diamond is reasonably brittle and a stone can be shattered with, for example, a hammer.
