3D lattice of C atoms, each attached to four others in a tetrahedral arrangement; all atoms are held in place by strong bonds and the atoms cannot move without breaking the bonds, so the structure is hard to break and cannot be bent 3D lattice of Na+ and Cl- ions; each Na+ surrounded by 6 Cl- and vice versa; water is a polar molecule; the Na+ ions are attracted to the negative pole and the Cl- ions are attracted to the positive pole Water can form hydrogen bonds, H2S can only form Van der Waal’s forces, hydrogen bonds are generally stronger
