Chapter 3, Problem 36A

Interpretation Introduction

Interpretation :

The example of non-metals that are found in the gaseous state needs to be given.

Concept Introduction :

The periodic table is divided into two forms one is a vertical column and the other one is horizontal. The elements are differentiated as metals, non-metals and metalloids. The physical properties such as density, tensile nature, and conductors for heat and electricity help to explain about the metals and non-metals.

Answer to Problem 36A

Most of the non-metals in the periodic table are found in the gaseous state. Some of the examples are: nitrogen, hydrogen, helium, fluorine, oxygen, chlorine, neon, argon, krypton, xenon, and radon.

Explanation of Solution

Non-metals are generally poor conductors of heat and electricity, and they are hard in nature.

The metals are generally found in a solid state. Most of the non-metals are found in a gaseous state, only bromine is present in a liquid state. Also, few are present in solid state like carbon, sulfur, iodine etc.

The examples of gaseous non-metals are nitrogen, hydrogen, helium, fluorine, oxygen, chlorine, neon, argon, krypton, xenon, and radon.

Conclusion

The right side elements in the periodic table are termed as non-metals. There majority of the non-metallic elements are gaseous in state, only one non-metallic element is present in liquid which is bromine. Also, few are present in solid state like carbon, sulfur, iodine etc.
