Concept explainers
Interpretation:
The figures and which should be a false statement from the given option.
Concept introduction:
A substance which can’t be divided into another substance, called element.
Answer to Problem 7STP
Correct answer: The correct option is (d).
Explanation of Solution
Reason for correct option: In the given diagram, figure C there is only two type of element are present one is lighter in shade and another one dark. So, this is not explaining the correct feature of the figure. Hence, this is a correct option.
Reasons for incorrect options:
Option (a) in the figure B is composed of two compounds. Compound is made up of two different elements. Which is correct representation for the compounds. Hence, this is an incorrect option.
Option (b) figure C is composed of two different compounds. The representation of compounds, the first one is composed of two elements and another one is composed of three elements. Hence, this is an incorrect option.
Option (c) figure B represents 13 total atoms. An element is made up of only one type of atom so there are only 13 atoms is present. Hence, this is an incorrect option.
