Reference: AQA
Bonds that hold atoms together within molecules, with shared electrons held between the atoms and not free to move through the substance.
Within a layer, each carbon has three single covalent bonds, so the layer is a continuous two-dimensional network.
A mechanism by which non-metal atoms achieve a full outer electron shell by sharing pairs of electrons.
The strong bonds that link the atoms within a polymer molecule to other atoms, forming the long chain.
Each carbon atom in graphite forms three covalent bonds, using three of its four outer electrons.
A bond formed when atoms share pairs of electrons, and this happens between non-metal atoms.
