How do you know which has a higher melting point?
In general, the greater the charge, the greater the electrostatic attraction, the stronger the ionic bond, the higher the melting point.
What elements have the highest melting points?
The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon.
What is the periodic trend for melting point?
Different groups exhibit different trends in boiling and melting points. For Groups 1 and 2, the boiling and melting points decrease as you move down the group. For the transition metals, boiling and melting points mostly increase as you move down the group, but they decrease for the zinc family.
Which group in the periodic table has the highest melting points?
Melting and boiling points across a period IVA group has the highest melting and boiling point element.
How do melting points compare to ionic compounds?
To compare 2 ionic compounds’ melting point, there are generally 3 determinants: Ionic Radii, smaller the ionic radius, closer the ions are to each other, therefore stronger the electrostatic attraction between them.
What is a high melting point?
A high melting point results from a high heat of fusion, a low entropy of fusion, or a combination of both. In highly symmetrical molecules the crystal phase is densely packed with many efficient intermolecular interactions resulting in a higher enthalpy change on melting.
Which one is the hardest element with highest melting point?
Of all metals in pure form, tungsten has the highest melting point (3,422 °C, 6,192 °F), lowest vapor pressure (at temperatures above 1,650 °C, 3,000 °F), and the highest tensile strength.
Which solid has highest melting point?
The melting point of the diamond is over 3500∘C, while the melting point of SiO2 is around 1650∘C. Covalent network solids are among the highest melting substances known. Metallic solids: Metallic solids are metal atoms that are held together by metallic bonds.
Why do different elements have different melting points?
Different solids have different melting points depending on the strength of bonding between the particles and the mass of the particles. Essentially, the heavier the particles in the solid, and the stronger the bonding, the higher the melting point.
What element has a melting point of?

Which element has highest melting point and why?
The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps.
Why do elements have different melting points?
