5 Fundamental Properties Of Nonmetals | Science Trends

Salt, for instance, has a melting point of 801 °C which is very high. However, compared to metals, nonmetal compounds do have relatively low melting.boiling points. Low melting and boiling points explain why the majority of nonmetals are gaseous at room temperature. Nonmetal compounds, specifically covalent compounds, have low melting and

True or False: Metals have a higher melting point than water

2019/06/21 · True or False: Metals have a higher melting point than water. The more energy needed, the higher the melting point or boiling point . As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. i would go with true.

why metals have high melting and boiling point?

Explanation: Metals have the highest boiling and melting points because they have the strongest chemical bonds which are metallic. The strongest chemical bonds require the most energy to break apart. Heat is measured in units of energy, so that's why the boiling point for metals require lots of heat.
