Lesson 3
Predict three facts you will learn about in Lesson 3. Look at the illustrations in the lesson to give you some clues. Write your facts in your Science Journal.
Nonmetals and Metalloids
Discuss the elements of life. Cross out the incorrect words in the parentheses.
The human body is made up of mostly (metals, nonmetals).
Ninety-six percent of the mass of the human body is composed of (oxygen, nitrogen, iron, carbon, silicon, copper), and hydrogen.
Explain nonmetals by completing the spider map.
Nonmetals are elements
that
.
Many nonmetals are in the
state at room temperature.
Solid nonmetals
have a surface; that is, they have no luster.
They are poor conductors but
.
Indicate which elements in groups 14–16 are nonmetals. Classify each of these elements as a solid or gas at room temperature.
Group 14 Group 15 Group 16
Recall the feature of the periodic table that helps to locate nonmetals.

More than 96 percent of the mass of the human body comes from four nonmetals–oxygen, carbon, hydrogen, and nitrogen.

Define metalloid.
Classify characteristics of metalloids as like metals and like nonmetals.
MetalloidsLike Metals Like Nonmetals
conduct electricity at temperatures
stop electricity from flowing at

Define semiconductor, and tell how it is useful.
Explain how knowing the position of an element on the periodic table can help you find a proper use for an element.

Without actually seeing the elements themselves, what can you infer from the positions of polonium and bismuth on the periodic table? How reactive do you think they might be? What do you think they might look like?

Open ResponseWrite your answer on the answer sheet provided.
Mei is working with an element that conducts electricity when it is hot but does not conduct electricity when it is cold. A crystal of the element is gray and shiny. Is Mei working with a metal, a metalloid, or a nonmetal? Explain your reasoning.
