4장, 문제 96c
Complete the following statements:
c. Elements that are shiny and conduct heat are called _____.
검증된 단계별 안내1
Understand the question: The problem is asking for the term used to describe elements that are shiny and conduct heat. This is a conceptual question related to the properties of elements in chemistry.
Recall the classification of elements: Elements are broadly categorized into metals, nonmetals, and metalloids based on their physical and chemical properties.
Identify the properties mentioned: The question specifies 'shiny' and 'conduct heat,' which are characteristic properties of metals.
Connect the properties to the correct term: Metals are known for their luster (shiny appearance) and their ability to conduct heat and electricity efficiently.
Conclude the answer: The term that fits the description provided in the question is 'metals.'
