Compared With the Melting Point Of Ionic Compounds The Melting Points Of Molecular Solids Tend To Be?

Ionic compounds have a higher melting point.


If both molecular solids and network solids contain covalent bonds why do network solids have such higher melting points than molecular solids?

Network solids have a three-dimensional structure with strong covalent bonds throughout, leading to a higher melting point compared to molecular solids which have weaker intermolecular forces. In network solids, a larger amount of energy is required to break the extensive network of covalent bonds, resulting in a higher melting point.

Why do some solids melt at higher temperatures than others?

The melting point of a solid depends on the strength of the bonds holding its particles together. Solids with stronger intermolecular or intramolecular forces require more energy input to break these bonds, resulting in a higher melting point. Factors such as molecular size, shape, and polarity can influence the strength of these bonds, leading to variations in melting temperatures between different solids.


What is the difference between a crystaline mineral and an amorphous mineral?

because amorphous solids are that solids that don't have geometrical shape and don't have particular melting point but crystalline solids have characterstic geometrical shape and have sharp melting point.


What is the Hypothesis of the melting and freezing point of naphthalene?

The hypothesis for the melting and freezing point of naphthalene could be that the melting point of naphthalene will be higher than its freezing point due to the typical behavior of most substances where solids melt at higher temperatures than they freeze. The hypothesis may also include factors like the purity of the naphthalene sample affecting its melting and freezing points.
