Materials with ionic or covalent bonds tend to be more easily scratched?

Ionic

Explanation:

Hello,

In this case, ionic bonds are more likely to be scratched since the molecules are more strongly bonded than those covalently bonded, due to the fact that as a result of that force, their structure will have a harder and more compact surface and inner assembly than those covalently bonded; consequently, it will be easier to scratch them.

Best regards.
