Which non-metal has very high melting point and boiling point?

Which non-metal has very high melting point and boiling point?

Detailed Solution. 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.

Which element has highest melting point?

The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps.

Which non-metal has a melting point of?

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

Which non-metal is highest melting point?

Diamond being the allotrope of carbon is a non-metal which possesses the highest melting point among all the non-metals. Among all other forms of carbon, diamond is extremely unreactive. They are typically colourless.

What is the highest melting point of any metal?

tungsten
Physical properties Of all metals in pure form, tungsten has the highest melting point (3,422 °C, 6,192 °F), lowest vapor pressure (at temperatures above 1,650 °C, 3,000 °F), and the highest tensile strength.

Which non metal has the highest melting point?

Does carbon have the highest melting point?

Moreover, carbon has the highest melting/ sublimation point of all elements. At atmospheric pressure it has no actual melting point as its triple point is at 10 MPa (100 bar) so it sublimates above 4000 K.

Does carbon have high melting point?

3,550 °C
Carbon/Melting point

Which non-metal has highest 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.

Is carbon a non-metal with extremely high melting point?

Carbon occurs in nature in a large number of allotropic forms. These mainly include the diamond, graphite, fullerenes, etc. Diamond being the allotrope of carbon is a non-metal which possesses the highest melting point among all the non-metals. Among all other forms of carbon, diamond is extremely unreactive.

What has a higher melting point metals or nonmetals?

Non-metals are bad conductor of electricity And are generally soft in nature. Therefore the melting point of metals is high whereas the melting point of nonmetals are low.
