Answer: Diamond is covalent crystal. It has the highest melting point because high energy covalent bonds hold the crystal together.
Explanation: Covalent bonds are very strong, so covalent network solids typically have the highest melting points out of all four types of solids.
Answer:
giant covalent solids
Ionic solids also have high melting points, often over 1000 degrees but they can vary. Some are often low enough to melt in the lab with a Bunsen burner:
