Metals With High Melting Points - Matmatch

Metals show a high melting point as they exist in a crystalline solid form. High melting point metals have strong intermolecular forces between atoms. Electrostatic attraction forces between metal ions and free electrons create strong metallic bonds with stronger bonds resulting in higher melting temperatures.
