Which of the following is a property of metals?
Group of answer choices
Good conductor
Dull
Low melting point
Brittle
Good conductor
The correct answer is "Good conductor" as it is a property of metals. To arrive at this answer, we can think about the characteristics of metals.
Metals are generally good conductors of heat and electricity. This is because their atoms have loosely bound outer electrons that are free to move between atoms, creating what is known as a "sea of electrons." This mobility of electrons allows metals to conduct heat and electricity easily.
On the other hand, the other choices - "Dull," "Low melting point," and "Brittle" - are not properties typically associated with metals.
"Dull" generally describes non-metallic materials that lack a shiny appearance. Metals, on the other hand, are often shiny due to their ability to reflect light.
"Low melting point" is not a typical property of metals. In fact, metals generally have high melting points, allowing them to maintain their solid form at ordinary temperatures.
"Brittle" is also not a characteristic of metals. While some non-metals may have a brittle nature (meaning they are prone to breaking or shattering easily), metals are usually malleable and ductile, meaning they can be bent, stretched, or shaped without breaking.
Therefore, based on these explanations, "Good conductor" is the correct property of metals.
