Draw a “formula” for each of the following molecules using circular symbols of your choice to represent atoms:
a. A diatomic molecule of an element
b. A diatomic molecule of a compound
c. A triatomic molecule of an element
d. A molecule of a compound containing one atom of one element and four atoms of another element
(a)
Interpretation:
The formula for the diatomic molecule of an element by using circular symbols to represent atoms is to be drawn.
Concept introduction:
A molecular formula represents the number of atoms of each element present in a molecule of a compound.
The number of atoms present in molecule is determined by the subscript written below the normal line in the molecular formula.
Answer to Problem 2.1E
The formula for the diatomic molecule of an element by using circular symbols to represent atoms is shown below.
Explanation of Solution
It is given that the molecule of an element is a diatomic which means that the compound consists of two atoms with similar identity. This can be explained with the help of one example. Considering a diatomic molecule of an element that is chlorine gas. The chemical formula of chlorine gas is
Therefore, the formula for the diatomic molecule of an element by using circular symbols to represent atoms is shown below.

Answer to Problem 2.1E
The formula for the triatomic molecule of an element by using circular symbols to represent atoms is shown below.
Explanation of Solution
It is given that the molecule of an element is a triatomic which means that the compound consists of three atoms with similar identity. This can be explained with the help of one example. Considering an example that is ozone. The chemical formula of ozone is
Therefore, the formula for the triatomic molecule of an element by using circular symbols to represent atoms is shown below.
