When looking across the periodic table from left to right, the first group to contain nonmetals is **Group 14**. This group includes elements such as carbon (C), which is a nonmetal, alongside silicon (Si), which is a metalloid, and germanium (Ge), which is also a metalloid.
To clarify the other groups:
- **Group 2** (alkaline earth metals) contains only metals.
- **Group 7** (halogens) contains nonmetals starting with fluorine (F) and chlorine (Cl).
- **Group 18** (noble gases) contains nonmetals.
However, Group 7 contains nonmetals like fluorine and chlorine, but they come after Group 14 in the periodic table. Therefore, Group 14 is the first group that introduces nonmetals.
