When looking across the periodic table from left to right which is the first group that contains nonmetals?

The first group that contains nonmetals as you move from left to right across the Periodic Table is Group 14, also known as Group IV or the carbon group. This group includes carbon (C), which is a nonmetal, along with silicon (Si) and germanium (Ge), which are metalloids. As you progress further right, you encounter additional nonmetals, such as nitrogen (N) and oxygen (O) in Groups 15 and 16, respectively.
