Substance with the highest melting point

For most substances, melting and freezing points are approximately equal. For example, the melting point and freezing point of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). However, certain substances possess differing solid-liquid transition temperatures. For example, agar melts at 85 °C (185 °F; 358 K) and solidifies from 31 °C (88 °F; 304 K); such direction dependence is known as hys… Web6 Sep 2024 · The reason why N a F would have the highest melting point is because, if you look at the electronegativity values fluorine has the highest hence it have the greatest pull or attraction towards the electrons in the …
