Chapter 3.4, Problem 24SSC

Interpretation Introduction

Interpretation:

Elements and compounds should be compared and contrasted.

Concept introduction:

Element is composed of similar types of atoms, while the compound is made up of two or more than two different elements. The elements not further breakdown but a compound can break into their elements.

Answer to Problem 24SSC

Elements and compounds are different from each other. Elements are present in compound formation but the compound is not present in the element formation.

Explanation of Solution

The elements are fixed in number till now, but there are numerous compounds in chemistry. There are many differences between elements and compounds both participated in a chemical reaction. Comparisonbetween Elements and compounds are mentioned below:

Element	Compound
Element is composed of pure and only one type of atoms.	The compound is made up of at least two or more than two different elements.
The numbers of elements are limited in the periodic table.	There are infinite numbers of compounds.
The element cannot be broken into their subparts.	A compound is the breakdown by simply chemical reaction and differentiated.
Examples as – oxygen, iron, aluminum, etc.	Examples as – sodium chloride, carbon dioxide, etc.

Conclusion

Some elements are only combined to form other compounds and the compounds by the chemical reaction the elements and new compounds are formed.
