1.49: Explain Why Substances with Giant Covalent Structures are Solids with High Melting and Boiling Points

GIANT COVALENT STRUCTURE: Contains many Non-Metal atoms joined to adjacent atoms by covalent bonds, forming a Giant Lattice Structure

s

SUBSTANCES WITH GIANT COVALENT STRUCTURES:

s

• STATES: Solids

s

• MELTING AND BOILING POINT: High Melting and Boiling Point as with many strong covalent bonds that needs to be broken down, large amounts of heat energy is needed to overcome forces and break down bonds
