Question

Which substance would have the highest melting point, based on electronegativity

Answer 1

Answer:

The substance with high electronegativity difference have high melting point.

Explanation:

Electronegativity:

                             It is a measure of the tendency of an atom to attract a bonding pair of electrons.

• Higher the electronegativity higher the potential to attract electron pair.
• So element with high electronegativity difference in elements tend to acquire the partial ions, attracting each other strongly.
• Hence more strong bonds substances would have highest melting points.

Answer 2

Electronegativity is the ability of an element to attract electrons towards itself during bonding. Compounds with a metal and nonmetal that have a great electronegativity difference would result to a much stronger intermolecular force. Its effect on the melting point is to increase it further because it takes greater energy to break these bonds. So, the higher the electronegativity difference, the higher the melting point.
