The chemical formula $NH_4NO_3$ represents a compound composed of nitrogen, hydrogen, and oxygen atoms. To determine the number of atoms of each element in this formula, we need to break down the formula and analyze its components.

Breaking Down the Formula

The formula $NH_4NO_3$ can be broken down into two main components: $NH_4$ and $NO_3$ . The $NH_4$ component represents an ammonium ion, which consists of one nitrogen atom and four hydrogen atoms. The $NO_3$ component represents a nitrate ion, which consists of one nitrogen atom and three oxygen atoms.

Analyzing the Components

Now that we have broken down the formula into its components, let's analyze each component separately.

Ammonium Ion ( $NH_4$ )

The ammonium ion consists of one nitrogen atom and four hydrogen atoms. This means that the $NH_4$ component contributes 1 nitrogen atom and 4 hydrogen atoms to the overall formula.

Nitrate Ion ( $NO_3$ )

The nitrate ion consists of one nitrogen atom and three oxygen atoms. This means that the $NO_3$ component contributes 1 nitrogen atom and 3 oxygen atoms to the overall formula.

Determining the Total Number of Atoms

Now that we have analyzed the components of the formula, let's determine the total number of atoms of each element.

Nitrogen: The ammonium ion contributes 1 nitrogen atom, and the nitrate ion contributes 1 nitrogen atom. Therefore, the total number of nitrogen atoms is 2.
Hydrogen: The ammonium ion contributes 4 hydrogen atoms. Therefore, the total number of hydrogen atoms is 4.
Oxygen: The nitrate ion contributes 3 oxygen atoms. Therefore, the total number of oxygen atoms is 3.

Conclusion

In conclusion, the chemical formula $NH_4NO_3$ represents a compound composed of 2 nitrogen atoms, 4 hydrogen atoms, and 3 oxygen atoms.
