Melting point is the temperature required to break the intermolecular bonds between molecules of a substance. This means that the bonds such as hydrogen bonds and polar attraction between the individual molecules of a substance must be broken so that the molecules can flow past each other in a liquid state. Diamonds have a very high melting point. This is because diamond is a macromolecule. Diamond is made up of single carbon bonds, with four carbons attached to each carbon molecule. In contrast, molecules such as water and carbon dioxide have a set number of atoms per molecule, and that number is very low. There are no intermolecular forces between diamonds molecules, so in order for diamond to become liquid the actual carbon bonds have to be broken.
This property of diamond makes it have a very high melting point. As heat is given to diamond, the energy is transferred throughout the molecule and dispersed by the huge number of bonds in diamond. It takes a very high melting point to finally break carbon bonds of a diamond molecule. Once carbon bonds begin breaking due to the extremely high heat, the molecules begins to melt.

Why is the melting point of diamond higher than sulfur?
The strong covalent bonds in the diamond structure make it more difficult to break down the lattice, requiring higher temperatures to melt. In contrast, sulfur forms weaker van der Waals forces between molecules, resulting in a lower melting point.
Why does Iodine have a low boiling point but diamond has a high boiling point?
Diamond is an allotrope of carbon where all the carbon atoms are tetrahedrally bonded with each other forming a three dimensional covalent network. Since the bonds are strong (covalent, network), diamond has a very high melting point and boiling point. Iodine does not have three dimensional network and hence has very low melting/ boiling point. It fact, it will sublime at room temperature.
Does the oxide of Barium have a high or low melting point?
Barium oxide has a high melting point of around 1,923 degrees Celsius. This is typical for many metal oxides, as they tend to have high melting points due to the strong ionic bonds between the metal and oxygen atoms.
Does platinum have a low melting point?
No, platinum has a high melting point of 1,768 degrees Celsius, making it one of the highest melting metals. This high melting point is one of the reasons why platinum is valued for its durability and resistance to heat.
Why does aluminum oxide have a high melting point?
Aluminum oxide has a high melting point because it has strong ionic bonds between aluminum and oxygen atoms. These bonds require a significant amount of energy to break, leading to a high melting point. Additionally, the structure of aluminum oxide is a giant ionic lattice, which further contributes to its high melting point.
What substance has a high melting point?
One substance that has a high melting point is diamond.
Can magma met a diamond?
The melting point of diamond is sufficiently high that magma would not melt it.
Why diamond is a non metal but it has high melting and boiling point?
Diamond is pure carbon with a specific crystalline structure.
What is a substance with a high melting point in which all the atoms are covalently bonded?
Diamond is a substance with a high melting point in which all atoms are covalently bonded. Diamond's structure consists of a network of carbon atoms, each bonded to four other carbon atoms in a tetrahedral arrangement, resulting in a strong covalent bond network that gives diamond its exceptional hardness and melting point.
Why has diamond have high melting point?
Diamond has a high melting point because of its strong covalent bonds between carbon atoms, which require a significant amount of energy to break. These bonds are arranged in a rigid lattice structure that makes it difficult for the atoms to move freely, resulting in a high melting point for diamond.
Why do diamonds have such a high melting point?
Diamond is the hardest natural mineral on earth. That this mineral has the highest melting point of any mineral -- 3820 degrees Kelvin -- is logical. You can read more about this mineral, below.
Why is diamond a unusual non metal?
Diamond is a unique nonmetal because its structure consists of a three-dimensional network of carbon atoms covalently bonded, making it extremely hard and having a high melting point. Additionally, diamond has a high refractive index and exceptional thermal conductivity, distinguishing it from other nonmetals.
Why diamond is very difficult to melts?
Diamond is difficult to melt because of its strong covalent bonds. These bonds are very strong, requiring a high amount of energy to break them and melt the diamond. Additionally, diamond has a very high melting point of about 3,500 degrees Celsius, further contributing to its difficulty in melting.
Does carbon have high melting point?
it has a low melting point
Does a metal have a high or low melting point?
All metals have different melting points but they are all high
Does chromium have a high low melting point?
Chromium has a high melting point of 1,857°C (3,375°F) making it a refractory metal.
Do solids have a high or low 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.
