WebA giant covalent structure is where a large number of atoms are joined by covalent bonds. A giant covalent structure involves lots of covalent bonds present between several atoms in a regular pattern forming a giant lattice. As lots of covalent bonds are present in the compound, the structure is extremely strong. It is called a macromolecule.
