Ionic bonds
electrostatic forces-apex
Covalent solids generally have lower melting points than ionic solids. This is because covalent solids are made up of discrete molecules held together by relatively weak intermolecular forces, whereas ionic solids are made up of ions held together by strong electrostatic forces. The weaker intermolecular forces in covalent solids require less energy to overcome, resulting in a lower melting point.
There are different forces that are associated with solids. The main ones are normal forces and ionic bonds which hold together ionic solids.
gravity
In the liquid the intermolecular forces between covalent molecules are weaker than the forces between ions.
Ionic solids are held together in a crystalline lattice, meaning that it is just a cluster of ions held together by their electrostatic attractions. ie. Na+ is represented by a +. Cl- is represented by a C. +C+C+C+C+C+C C+C+C+C+C+C+ +C+C+C+C+C+C Here we can see that the C's are surrounded by the positively charged +'s and vice versa.
Ionic compounds conduct electricity as liquids and in solution.
Gold and platinum are not ionic solids, they are metals held together by metallic bonds not ionic bonds.
Strong chemical bonds in solids are ionic bonds, covalent bonds in giant network molecules and metallic bonds. Weak bonds in solids holding discrete molecules together are hydrogen bonds in solid H2O, HF, NH3 Weak intermolecular forces including dispersion forces and permanent dipole interactions
No, they do not hold two compounds together. The forces that hold compounds together are intermolecular forces. Ionic and covalent bonds are intramolecular forces, and they hold the atoms of the molecule or formula unit together.
