WebBond percolation is studied for the three homogeneous two-dimensional lattices: square lattice (SL), triangular lattice (TL) and honeycomb lattice (HL). An expanding cell technique is used to obtain percolation thresholds and other relevant information for different cell sizes. WebHere is a short list of main properties: They form crystals. Ionic compounds form crystal lattices rather than amorphous solids. They have higher enthalpies of fusion and vaporization than molecular compounds. They are hard. They are brittle. They have high melting points and also high boiling points. They conduct electricity but only when they ...
