the subscript 3 represent the amount of H (hydrogen) in ammonia.
The chemical formulas represent the proportion of atoms present in the structure of the same.
Chemical formulas use letters and numbers to represent chemical species.
The letters are called the chemical symbol and represent the elements present in the chemical species.
The subscripts placed to the right of a symbol are numbers that indicate the number of atoms of the element present in that compound. If there is no subscript after a chemical symbol, this implies that there is only one atom of that element.
So, in the chemical formula for ammonia, NH₃, you can know that the compound is made up of 4 atoms:
- N= nitrogen: 1 atom
- H=hydrogen: 3 atoms
Finally the subscript 3 represent the amount of H (hydrogen) in ammonia.
