Verified step by step guidance1
Understand the classification of elements into metals, nonmetals, and metalloids based on their properties such as conductivity, luster, and state at room temperature.
Recall that standard temperature and pressure (STP) refers to 0°C (273 K) and 1 atm pressure, and consider the physical state of each element at these conditions.
Identify the physical state of each given element at STP: Sodium (Na) is a metal and solid, Neon (Ne) is a noble gas and gas, Sulfur (S) is a nonmetal and solid, Bromine (Br) is a nonmetal but liquid.
Focus on the elements that are nonmetals and check their states at STP; Sulfur (S) is a solid nonmetal, while Bromine (Br) is a liquid nonmetal, and Neon (Ne) is a gas.
Conclude that the element classified as a nonmetal and solid at STP among the options is Sulfur (S).
