Answer: When the electrons in an element are more than the required, a bond is formed with other element which has deficiency of electron and in case when electrons are less in numbers the vice versa happens. Such kind of chemical bonds are known as ionic bond.
Explanation:
There are 2 molecules of Carbon dioxide(CO2)
<h3>Further explanation</h3>
Given
Molecules of CO2
