what are nonmetals in period 3?

In Period 3 of the Periodic Table, the nonmetals include phosphorus (P), sulfur (S), chlorine (Cl), and argon (Ar). These elements exhibit varied physical and chemical properties; for instance, phosphorus and sulfur are solid at room temperature, while chlorine is a gas and argon is a noble gas. Nonmetals in this period typically have higher electronegativities and ionization energies compared to metals, and they tend to form covalent bonds and anions in chemical reactions.
