To accurately classify the elements highlighted in green, I need to know which specific elements you are referring to, as the classification can vary based on the context (e.g., the periodic table). However, in general terms associated with the periodic table:
- Metals tend to be located on the left side and in the center of the periodic table.
- Nonmetals are found on the right side of the periodic table.
- Metalloids have properties of both metals and nonmetals and are found along the zig-zag line.
- Chemicals is a broad term that can refer to any substance, so it’s not a specific classification in this context.
If you provide the specific elements or the context in which they are highlighted, I can give a more accurate classification.
