Source sentences:
text: Before graphene was isolated, it was commonly believed that two dimensional compounds could not exist because they would be too unstable, but the carbon-to-carbon bonds in graphene are small and strong and completely stable.
text: In graphite, the bonds between nearest neighbors are even stronger but the bonds between planes are weak, so the planes can easily slip past each other.
text: Conversely, bonds to other atoms are very strong because of fluorine's high electronegativity.
text: As is true with carbon, the bonds in elemental silicon are strong enough to require large energies to activate, or promote, reaction in an acidic medium, so it is unaffected by acids except hydrofluoric.
text: Tetrahedra are rigid, the bonds are strong, and of all known substances diamond has the greatest number of atoms per unit volume, which is why it is both the hardest and the least compressible.
