Question

question 3. metals, metalloids, and nonmetals are essential categories of elements found on the periodic table, each with unique properties that influence their applications. metals are typically shiny, malleable, ductile, and excellent conductors of heat and electricity, making them ideal for construction and electrical wiring. metalloids possess mixed characteristics; they are often semiconductors, which makes them critical in the electronics industry for devices like computers and smartphones. nonmetals, on the other hand, tend to be dull, brittle, and poor conductors, yet they play vital roles in biological processes and the atmosphere, such as nitrogen in the air and oxygen for respiration. based on the passage, identify and describe the key properties of metals, metalloids, and nonmetals. provide specific examples of each category and explain how their properties make them suitable for particular uses in everyday life.

Explanation:

Metals are shiny, malleable, ductile, and good heat - electricity conductors (e.g., copper for wiring). Metalloids are semiconductors (e.g., silicon in electronics). Nonmetals are dull, brittle, poor conductors but important in biology and atmosphere (e.g., nitrogen and oxygen).

Answer:

Metals: Key properties - shiny, malleable, ductile, good conductors of heat and electricity. Example: Copper, used for electrical wiring due to its excellent conductivity.
Metalloids: Key property - often semiconductors. Example: Silicon, used in computers and smartphones as a semiconductor material.
Nonmetals: Key properties - dull, brittle, poor conductors. Example: Nitrogen in the air and oxygen for respiration, playing vital roles in biological processes and the atmosphere.
