The melting point of metal depends on the type of metal. In general, metals have high melting points compared to other substances. For example, the melting point of iron is 1538 ˚C (2790 ˚F), while the melting point of water is 0 ˚C (32 ˚F).
The melting point of a metal is often determined by its atomic structure. Metals typically have strong intermolecular forces that require a significant amount of energy to break them down, resulting in a high melting point.
By comparison, substances with weaker intermolecular forces, like water, have lower melting points since the required energy to break them down is less.

Are metals high melting point?
Yes, metals generally have high melting points. Most metals have melting points significantly above 1000°C. Metals have strong intermolecular bonding forces, due to their metallic lattice structure and positive ions.
It takes a lot of energy to break the bonds of metal lattice structures, which is why the melting point of most metals are so high. For example, the melting point of copper is 1083°C and for iron it is 1538°C.
However, some metals such as mercury have low melting points that are below room temperature.
Why do metal melt at high temperature?
Metal melts at high temperatures due to the heat energy that is applied to the metal. When heat energy is applied, the molecules within the metal begin to vibrate and move around more rapidly. This rapid movement of the molecules causes the atoms to collide with each other, which increases the pressure and forces the molecules to move apart.
As the molecules and atoms move apart, the metal loses its structure and takes on a liquid form. The melting point of a metal is determined by the type of metal and the strength of the forces that hold the molecules together.
The more tightly bound the molecules are, the higher the temperature that is required to break down the structure of the metal.
Why does metal melt and not burn?
Metal does not burn because it does not react chemically with oxygen. Instead, it must reach a high temperature in order for it to melt at which point, it transitions from a solid to a liquid state. Melting points for metals vary greatly depending on the type of metal and can range from low temperatures like -180°C (for Mercury) to extremely high temperatures like 1870°C (for carbon).
When metal reaches the extreme temperatures necessary to melt, it has absorbed enough energy for its individual atoms to break apart which allows it to transition into the liquid state.
Why melting point increases down the group for non-metals?
The melting point of a non-metal increases as you move down a group on the periodic table. This is due to the increasing size and weight of the atoms as you move down the group. As the atoms get heavier, they contain more electrons, which makes them harder to break apart.
The extra electrons increase the attraction between the atoms, and it takes more energy to break apart the bonds. This increases the melting point for the non-metal, since increased energy is needed to separate the atoms, allowing them to liquefy.
The increased size of the atoms also results in more space between them and stronger repulsive forces – again making them harder to break apart. This further increases the melting point.
Why the melting point of metal is high?
The melting point of metals is high because of the strong bonds between the atoms in each metal. Metals are densely packed, meaning the atoms that make up the metal are closely bound together. This means the connections between the atoms are very strong, resulting in a higher melting point than most other materials.
Metals also possess a great deal of thermal energy due to the vibrational motion of the atoms, further increasing their melting point. By contrast, non-metallic materials such as polymers or ceramics are made up of less densely packed molecules so their melting point is much lower than that of metals.
Is low melting point a metal or nonmetal?
A low melting point does not necessarily specify whether an element is a metal or nonmetal. For instance, both metals and nonmetals can have low melting points. Metallic tin, for example, has a melting point of 232.
9°C (449. 2°F), which is considered low compared to other metals. On the other hand, some nonmetals such as bismuth have an even lower melting point of 271. 3°C (520. 3°F). Generally, nonmetals have lower melting points than metals because of their weaker intermolecular forces.
Why metals are hard and have high melting?
Metals have a strong network of metallic bonds which helps to make them hard and have a high melting point. Metal bonds are stronger and more difficult to break because metal atoms have more free electrons in their outer shells that allows them to interact more strongly between each other.
The more free electrons that are present, the stronger the strength of the bond. The more electrons, the more attractive force pushing atoms closer together creating harder and stiffer materials. At the same time, these strong metal bonds also require more energy to break them apart, which makes it harder for metals to melt at lower temperatures.
