Question

1. classify the following elements as metals, nonmetals, or metalloids. include one characteristic/property of each type. ar, h, al, na, te, f (6 pts) metals nonmetals metalloids property of metals: property of nonmetals: property of metalloids:

Explanation:

• Metals: Aluminum (Al) and Sodium (Na) are metals. Metals are generally good conductors of heat and electricity. For example, aluminum is used in electrical wires due to its high electrical conductivity, and sodium has a metallic luster and can conduct heat (e.g., in some heat - transfer applications in specialized reactors).
• Nonmetals: Argon (Ar), Hydrogen (H), and Fluorine (F) are nonmetals. Nonmetals typically have poor thermal and electrical conductivity. Argon is an inert gas (a non - metal) and is a very poor conductor of electricity (used in incandescent light bulbs to prevent filament oxidation without conducting electricity). Hydrogen is a gas at room temperature and is a non - conductor (in its elemental form, it does not conduct electricity like metals). Fluorine is a highly reactive non - metal gas and is a poor conductor.
• Metalloids: Tellurium (Te) is a metalloid. Metalloids have properties intermediate between metals and nonmetals. Tellurium has some metallic luster (like a metal) but is also a semiconductor (a property more similar to nonmetals in terms of electrical conductivity, which is not as high as metals but higher than most nonmetals).

Answer:

Metals	Nonmetals	Metalloids
Property of Metals: Good conductors of heat and electricity	Property of Nonmetals: Poor conductors of heat and electricity	Property of Metalloids: Semiconducting properties (intermediate between metals and nonmetals)
