The melting point of a substance depends, in part, on whether one or more intermolecular forces act to attract the molecules of the substance, and on the strengths of these forces. In the cases of the substances you mention these forces are absent or very small.
They have low melting points and high reactivity.
Yes, molecular solids have relatively low melting points.
They have high melting points
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.
No, ionic solids have very high melting points. Ionic solids are one of the strongest bonds formed among elements.
No, they have very low melting.
Methane has an extremely low melting point. This is due to weak intermolecular attraction.
They have low melting points and high reactivity.
Yes, molecular solids have relatively low melting points.

Yes non metals do have high melting and boiling points. This is because they have strong intemolecular forces that are hard to overcome.A2. Their melting points vary. Obviously gases such as nitrogen and oxygen have low melting points, but Silicon (1414oC) and Diamond ( around 1700oC) are rather high. Phosphorous and Sulfur on the other hand are rather low.
No
Alkali metals have relatively low melting points compared to the other metals. Their exact melting points depend on the element itself. But it would be useful to note that their melting points decreases down group I.
They have high melting points
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.
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.
Yes.
