D
Explanation:
An example is a chemical formula of a compound NH₄NO₃
These subscript numbers mean that there four (4) hydrogen atoms and three (3) oxygen atoms in the molecules.
A Lewis dot diagram for the molecule is used to show the electrons of the atoms, and their interactions – such as in covalent bonding- in the molecule
The chemical formula for a molecule has, representing the number of atoms of each element in a molecule. Thus, option D is correct.
The chemical formula has been the representation of the molecule for the determination of the chemical proportion of the atoms.
The number of atoms has been of each element has been present with the bonding with other element in the chemical formula.
It has been written as the chemical symbols of the elements, with subscript at the base of the element. The subscript has been the representation of the number of atoms of elements.
Thus, with the application of chemical formula, the number of atoms of each element in a molecule has been determined. Thus, option D is correct.
