WebIt is possible for many atoms to link up to form a giant covalent structure or lattice. The structures of giant covalent structure are usually based on non–metal atoms like carbon, silicon and boron. The atoms in a giant covalent lattice are held together by strong directional covalent bonds and every atoms is connected to at least 2, 3 or 4 ... WebIn certain substances, thousands of atoms join together by covalent bonding producing giant covalent structures. All the bonds in giant covalent structures are covalent, which means gives them very high melting and boiling points. In addition, almost all giant covalent structures are hard but brittle. Carbon allotropes. In carbon the atoms can ...

WebThe giant moleculars are graphite, diamond, silicon, silicon dioxide, silicon carbide, boron and a few (ish) others.
