The chemical formula for ammonium nitrate is NH4NO3. It consists of 3 elements: nitrogen, hydrogen and oxygen.
There are two elements in CO2, carbon and oxygen.
Oxygen and hydrogen
In compounds with elemnts with low electronegativity compounds N3-, P3- etc are found.

...as a solid.
The columns organise the elemnts according to the number of valence electrons that give rise to many of the similarities between the chemistry of the elemnts in the column. The rows organise in increasing atomic number.
NH4 contains two different elements. They are nitrogen (N) and hydrogen (H).
Out of the 100 elements in existence, only water and oxygen are necessary for survival.
Carbon and hydrogen, CH4
Noble gases
