Some do while others do not. To be solid a substance must merely have a melting point that is above room temperature. Gallium has a melting point just above room temperature, so it is normally solid but it will melt in the palm of your hand. By contrast Tungsten has such a high melting point that not even the hottest lava from Earth's volcanoes can come close to melting it.
Amorphous solids have no definite melting point because their particles are arranged randomly. Amorphous solids do not have crystal form or definite melting point.
You think probable to a glass.
it has a low melting point
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.
Name this crystalline solid; each compound and material have a different melting point.
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.

Low Melting Point. Most metals have high melting point and are solids at room temperature.

the melting points differ to differant solids
Covalent compounds have a lower melting point.
low melting point
Covalent compounds have a lower melting point.
Ionic compounds have a higher melting point.
No, ionic solids have very high melting points. Ionic solids are one of the strongest bonds formed among elements.
