Which non-metal has high melting and boiling point?

The non-metal, carbon in diamond form, is the hardest substance due to the strongest interaction among the carbon atoms. Hence, it is carbon in diamond form which has very high melting and boiling points.

Which non-metal has a melting point of?

Graphite, a form of carbon (a non-metal), has a high boiling point and exists in the solid state at room temperature….Physical properties of metals and non-metals.

Metals	Non-metals
High melting points	Low boiling points
Good conductors of electricity	Poor conductors of electricity

Which non-metal is high boiling point?

The correct answer is graphite. Graphite, a form of carbon (a non-metal), has a high boiling point and exists in the solid-state at room temperature. It is also a good conductor of electricity.

Why do nonmetals have a low melting point?

A lot of nonmetals, like oxygen and chlorine are highly electronegative: they have high affinity for electrons and effectively pry them from the other atom, so the bond breaks easily. As a result, these nonmetals have subzero melting point temperatures.

Do nonmetals have a high density?

Nonmetals, on the right side of the periodic table, are very different from metals. Their surface is dull and they are poor conductor of heat and electricity. As compared to metals, they have low density and will melt at low temperatures.

Does Aluminium have high melting point?

1,221°F (660.3°C)
Aluminium/Melting point

Do metalloids have high melting points?

Metalloids are the borderline between metals and non-metals. For example some metalloids can have a high melting point (like a metal) yet have a low density (like a non-metal). The metalloids are Boron, Silicon, Germanium, Polonium, Tellurium, Astatine, Arsenic, and Antimony.

Does non-metals have low melting point?

Melting and boiling points of non-metals are low as compared to metals. Metals are a good conductor of electricity and generally all metals are hard except sodium and potassium. Therefore the melting point of metals is high whereas the melting point of nonmetals are low.

Which non-metal has highest density?

As Javad Ahmed noted, iodine has the highest density (among the commonly encountered nonmetallic elements).
