Verified step by step guidance1
Identify the elements listed in the problem: Carbon, Oxygen, Sulfur, Radon, and Cesium.
Understand the classification of elements: Metals, Nonmetals, and Metalloids. Nonmetals are typically found on the right side of the periodic table and have properties such as being poor conductors of heat and electricity.
Recognize that nonmetals can exist in different forms, including diatomic and polyatomic forms. A polyatomic solid is a solid composed of molecules containing more than two atoms.
Review the properties of each element: Carbon can form polyatomic structures like graphite and diamond, Oxygen is a diatomic gas at room temperature, Sulfur is a polyatomic solid, Radon is a noble gas, and Cesium is an alkali metal.
Conclude that Sulfur is the nonmetal that is a polyatomic solid, as it commonly exists in the form of S8 rings in its solid state.
