There is a total of 17 elements in those groups.
nitrous oxide, or N2O contains two elements, Nitrogen and Oxygen
Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group elements.

Carbon
Group 18, the noble gases, are elements that hardly react with other elements. This is because they have their full complement of eight valence electrons.
The ground state of Oxygen contains only eight electrons in only the first two energy levels.
