Final answer:
The assertion that Noble Gases, Halogens, and Non-Metals form the last group is false; Noble Gases are in Group 18, Halogens are in Group 17, and they are distinct within the nonmetals category.
Step-by-step explanation:
The statement that the last group consists of Noble Gases, Halogens, and Non-Metals is false. In the periodic table, the Noble Gases are found in Group 18 and Halogens are found in Group 17. These two groups fall within the broader classification of nonmetals, but they are distinct groups with unique properties.
Noble gases are known for being the least reactive due to their filled valence shells, while halogens are highly reactive as they are just one electron short of a full valence shell. Therefore, the correct grouping would be that Noble Gases and Halogens are separate groups within the nonmetals.
