Final answer:
Metals are characterized by their malleability, excellent electrical conductivity, and shiny appearance, which are all essential properties that make them valuable in various applications, including electrical wiring and jewelry making.
Correct options are B. malleable , C. good conductors of electricity , D. shiny.
Step-by-step explanation:
Three characteristics of metals include being malleable, having the ability to conduct electricity, and possessing a shiny appearance. Metals are known for their ability to be deformed under pressure without breaking, which is termed malleability. This property allows metals to be hammered into sheets or bent into various shapes. Additionally, metals are excellent conductors of electricity due to the movement of free electrons within their structure.
This makes metals ideal for use in electrical wiring and components. Lastly, metals typically have a shiny or lustrous surface, which makes them visually distinct and useful in applications where aesthetics are important, such as jewelry making.
Correct options are B. malleable , C. good conductors of electricity , D. shiny.
