Question

melting points of non metals​

Answer 1

Answer:

Melting and boiling points: All non-metals, have low melting and boiling points. The melting point of sulphur (S) is 115°C. Graphite and diamonds have high melting points, but these are exceptions in the non-metals.

Solubility of non-metals : Non-metals are soluble in some chemical or organic solvents. For example iodine (I) is soluble in alcohol.

Density of non-metals: Non-metals have low densities as compared to metals, which have high densities. This means that in non-metals, the atoms are not strongly bound. The crystalline volume of non-metals is small.

Non-metals are not sonorous: Non-metals do not make any characteristic sound when hit with an object. Thus non-metals are not sonorous.

Explanation:

Their melting and boiling point are usually low. The exceptions are boron, carbon and silicon.
