No, ionic solids have very high melting points. Ionic solids are one of the strongest bonds formed among elements.
Yes, molecular solids have relatively low melting points.
They have high melting points
The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic (or covalent) bonds.
No. They have very high melting points because they are extremely strong. This is because of the transfer of electrons between the atoms in the bond. Molecular generally have low melting points.
Ionic compounds have strong electrostatic force of attraction and hence have higher melting points than covalent compounds.
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound
Yes, molecular solids have relatively low melting points.
They have high melting points
Silvery solids with low densities and low melting points are alkali metals. These are located in group one on the periodic table.

That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
The bonds in the molecule are weaker.
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.

The covalent bond is not so strong as the ionic bond.
