Did you know?
WebIt is because diamond crystallize on what we call atomic crystal structure, which means that when it is in a solid state, there are atoms held together by strong covalent bonds. Diamond has a 3D network involving strong C-C bond which are very difficult to break and,in turns has high melting point. WebAug 14, 2024 · To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically characterized by hardness, strength, and high melting points. For example, diamond is one of the hardest substances known and melts above 3500 °C. Figure \(\PageIndex{5}\).
