Semi-conductors have properties of both metals and nonmetals. Which are two examples of metalloids?

A. Ge and SiB. C and SiC. O and GeD. Al and Si

According to the article, why are metals not used on transistors and integrated circuits?

A. Metals can’t be found very easily

in nature.

B. Metals are not malleable

C. Metals are too expensive

D. Metals are tough to control the

flow of electric current.

Why is silicon a better

choice for computer chips than germanium?

A. Germanium is not a semi-

conductor

B. It’s easier to work with

C. It’s cheaper

D. It can resist much higher

temperatures

Which element is the

second most abundant

element found on Earth?

A. Oxygen

B. Carbon

C. Silicon

Which side of the periodic

table are the metals on?

Which side of the periodic

table are the nonmetals on?

Describe the difference

between Luster and Dull.

What physical property do

metals have?

1. Click Play on the video.

2. Answer questions from cards

#2-4 on your lab sheet.

YouTube

What does the term

malleable mean?

Which is more malleable,

metals or nonmetals?

1. Go to http://goo.gl/GriHF4

2. On the left hand side click #2 Metals vs.

Nonmetals

3. On your lab sheet use your

own words to describe the

differences between the silver

and the sulfur. Use at least 3

characteristics for each.

1. Use the interactive game at the

bottom to try and classify metal

and nonmetal characteristics.

2. List 3 of each on your lab sheet.

2. Watch the video at the

bottom.

3. What are three uses for

metalloids?

1. On the left hand side

click #3 Metalloids

1. Use the cards on the table and organize them into two stacks.

2. On your lab sheets describe why you organized them the way you did.

The correct stacks should look like

Metals: gold, copper, magnesium, lithium, silver

Nonmetals: oxygen, carbon, neon, argon,

chlorine

Each of the images is an element and can be classified as a metal or nonmetal.

Metals have their own unique physical and chemical properties.

1. Look at the stack of cards that are metals and list 3 characteristics they share on your lab sheet.

Nonmetals also have their own unique physical and chemical properties.

1. Look at the stack of cards that are nonmetals and list 3 characteristics they share on your lab sheet.

One category we haven’t

talked about is metalloids.

Metalloids have properties

of both metals and

nonmetals and are found

near the “staircase” on the

periodic table

2. Good conductors – metals can conduct

heat and electricity well.

3. Ductile – Many metals can be pulled into a

wire like Copper.

4. Malleable – Many metals can be pounded

in a sheet like Aluminum

5. Mostly solid – Most metals are solids.

Metals have many similar

properties. Copy the list down on

your lab sheet.

1. Shiny luster – This is the ability of

the element to reflect light. Metals

are often shiny.

2. Poor conductors – nonmetals do not

conduct heat and electricity well.

3. Brittle – Many nonmetals can break easily.

4. Mostly gas – Many metals are made of gas

although some are solid.

Nonmetals have many similar

properties also. Copy the list

down on your lab sheet.

1. Dull – these elements often

have a dull (not shiny)

appearance.

Gold Copper Magnesium Lithium Silver

Oxygen Carbon Neon Argon Chlorine

On your lab sheet color in the metals, nonmetals and

metalloids. HINT: It makes it a lot easier if you start with

the metalloids. Be sure to include a legend.
