Metals have high melting and boiling points compared to non-metals because they are good conductors of heat and electricity, while non-metals are poor conductors of heat and electricity. Metals are solids at room tempera... More »

Among the elements grouped as metals, mercury has the lowest melting point at minus 38.83 degrees Celsius. Mercury has a very wide temperature range in its liquid state, according to Jefferson Lab, with a boiling point o... More »

The melting point, also known as the freezing point, of a metal is the temperature at which it changes from a solid to a liquid. At the melting point, the substance is able to exist as both a solid and liquid in equilibr... More »

Metals are generally lustrous, are able to conduct heat and electricity, have high melting points, are malleable, remain solid at room temperature and appear opaque in thin cross-sections. Non-metals have a dull appearan... More »

Most metals are solids at room temperature as they have high melting points. Mercury is the only metal that occurs in liquid form at this temperature. More »

Ionic compounds have high melting and boiling points because the ionic bonds that hold the compounds together are very strong and require a great deal of energy to break apart. A higher temperature indicates that more en... More »

Sodium chloride has a high melting point because of the strong electrostatic attraction between its positive and negative ions; this requires more heat energy to overcome. All ionic compounds have high melting points for... More »
