Chapter 17.2, Problem 7R

To determine

To Explain: The solid nonmetals are different from the solid metals.

Explanation of Solution

Introduction:

In the periodic table, there are 10 non-metals which are solids.Some of these are-Boron, Carbon, Silicon, Phosphorus, Arsenic, Sulphur, Iodine.

Metals are highly malleable as their shape changes easily. They conduct the heat as well as the electricity. Metals have higher melting point generally. On the other hand, non-metals are dull and brittle, and these are the poor conductors of heat and electricity. These easily undergo sublimation and have low melting point.

Conclusion:

The solid nonmetals are different from the solid metal. non-metals have lower melting point while metals have higher melting point. Metals conduct the heat and electricity to large extent while non-metals do not conduct the heat and electricity. The solid non-metals easily undergo sublimation and have low melting point.
