NaCl does, by virtue of the fact that sodium is the smallest of the three ions; sodium, potassium, rubidium. Since it is the smallest, the ions are close together, generating larger attractive forces, and holding the atoms more tightly. Therefore more heat is needed to melt it. Aluminum, on first blush, should have the highest, because of the largest charge (+3). However, aluminum is also significantly less electronegative than the other three, and so there is more covalent character in aluminum chloride than in the other three. In other words, AlCl3 resembles sugar more than it does salt in its resistance to heat. As such, it is the lowest melting of the four.
The mineral with the highest known melting point is tungsten, which has a melting point of 3,422 degrees Celsius.
Magnesium has a higher melting point.
A substance's melting point is the temperature at which it changes from a solid to a liquid state. It is unique to each substance and does not necessarily match the melting point of any other substance.
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.
Yes, all substances have unique boiling and freezing points that are determined by their chemical composition and properties. These points represent the temperature at which a substance changes its state from liquid to gas (boiling point) or from liquid to solid (freezing point).
the highest temperature in which a solid substances turns into a liquid without any change in its chemical contents
No. Carbon has the highest melting point.

Carbon (C) has the highest melting point out of all the elements, and so, as it's in the first 20 elements, it has the highest melting point of the first 20 elements too. Its melting point is 3823K.
The element with the highest melting point in its group is carbon. Specifically, graphite has the highest melting point among the carbon allotropes, which is higher than the melting points of other elements in its group.
After Carbon (in form of diamond), the element Tungsten (W) has the second highest melting point of 3695 K, 3422 °C, 6192 °F
The natural element with the highest melting point is good old Carbon! Its melting point is 3527 degrees, C. The element with the second highest melting point is Tungsten at 3422 degrees, C.
Substances with ionic bonds, such as ionic compounds like salts, typically have the highest melting points due to the strong electrostatic forces between the ions. Examples include sodium chloride (table salt) and magnesium oxide.
Highest melting point. (Note that this does not assure that the remaining compounds are not also ionic.)
carbon has the highest melting point of elements.its melting point is around 3900 degree Celsius
No. The element C (carbon) is a nonmetal, not a metal. It does have the highest melting point of all the elements, though.
The mineral with the highest known melting point is tungsten, which has a melting point of 3,422 degrees Celsius.
