Metals, Nonmetals, & Metalloids - Science PAP - 8th Grade - Bernal Middle School

What does conductivity mean?

Conductivity is the ability of the substance to conduct electricity. This may be tested with a conductivity meter.

What does ductility mean?

Ductility is the ability of the substance to be pulled into a thin wire.

How are elements represented on the Periodic Table?

Elements are represented on the Periodic Table with chemical symbols.

What does luster mean?

Luster is the ability of a substance to reflect light. Usually the descriptive words are either metallic or non-metallic.

What does malleability mean?

Malleability is the ability of a substance to be hammered into sheets without breaking.

Where are metalloids found on the Periodic Table?

Metalloids are found along the zig-zag on the Periodic Table.

Describe metalloids.

Metalloids have no set characteristics, they share properties of both metals and nonmetals.

Describe metals ductility.

Metals are ductile and can be drawn into wire, but some are more ductile than others.

How are metals found on the Periodic Table?

Metals are found to the left of the zig-zag on the Periodic Table.

Describe metals conductivity and luster.

Metals are good conductors of electricity and heat (but some are better conductors than others). Metals are metallic looking with a shiny luster.

Describe metals malleability.

Metals are malleable and can be hammered into sheets without breaking.

Describe metals.

Metals are solid at room temperature, except for mercury, which is a liquid.

Describe nonmetals malleability.

Nonmetals are brittle when they are solid.

Where are nonmetals found on the Periodic Table?

Nonmetals are found to the right of the zig-zag on the Periodic Table.

Describe nonmetals luster.

Nonmetals are not metallic looking, have a dull luster and do not reflect much light.

Describe nonmetals conductivity.

Nonmetals are poor conductors or electricity and heat.

What are the forms of nonmetals?

Nonmetals are solid, liquid or gas at room temperature.

What are some of the physical properties used to distinguish between the three groups?

Some of the physical properties used to distinguish between the three groups are as follows: 1. Luster 2. Conductivity 3. Malleability 4. Ductility

What is the only exception to the metalloids which are found along the zig-zag?

The only exception is Aluminum. It is considered to be a metal even though it lies along the zig-zag.

What are the three large groups elements are classified into on the Periodic Table?

The three large groups elements are classified into on the Periodic Table are metals, nonmetals, and metalloids.

True or False: Elements within each group have similar physical and chemical properties.

True

True or False: Metalloids may have a shiny luster, but be poor conductors and brittle

True. Metalloids have no set characteristics, they share properties of both metals and nonmetals.
