Where are the majority of nonmetals found on the periodic table?

The majority of nonmetals are found on the right side of the periodic table, primarily in groups 14 to 18. They occupy a distinct region separated from metals by a “stair-step” line, which starts near boron (B) and extends downward to polonium (Po). This line marks the transition between metals and nonmetals, with metalloids acting as a bridge. Nonmetals include essential elements like oxygen, nitrogen, and carbon, and they tend to have high electronegativities and poor electrical conductivity. Hydrogen, though technically a nonmetal, is an exception, as it is positioned in the top-left corner of the periodic table.
