Giant covalent structures are brittle and shatter when hit this statement is true.
Hence, Option D is correct answer.
Ionic bonds is a chemical bond formed when one atom transfer its valence electron to another atom. Ionic bond is also called electrovalent bond. These bonds are stronger.
The 3-D structure of atom which are joined by covalent bond is called giant covalent structure. Giant covalent substances are brittle and they shatter when hit because covalent bond break at once. Giant covalent structure have very high melting and boiling point.
A larger ionic charges in a compound makes a weaker ionic bond. The larger ions have high melting point.
Thus from the above conclusion we can say that Giant covalent structures are brittle and shatter when hit this statement is true.
Hence, Option D is correct answer.
