Front

What are nonmetals?

Back

Nonmetals are elements found to the right of the zig-zag line on the periodic table. They are generally poor conductors of heat and electricity and have properties opposite to metals.

Front

What are metals?

Back

Metals are elements that are typically shiny, malleable, ductile, and good conductors of heat and electricity. They are found to the left of the zig-zag line on the periodic table.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals. They are found along the zig-zag line on the periodic table.

Front

What does it mean for an element to be a good conductor?

Back

A good conductor is a material that allows electricity or heat to flow through it easily. For example, metals like copper and aluminum are good conductors.

Front

What are coefficients in a chemical equation?

Back

Coefficients are the numbers placed before compounds in a chemical equation that indicate how many molecules or moles of that substance are involved in the reaction.

Front

What are subscripts in a chemical formula?

Back

Subscripts are the small numbers written after an element in a chemical formula that indicate the number of atoms of that element in a molecule.

Front

How can you test if a material is a good conductor?

Back

You can test if a material is a good conductor by connecting it in a circuit with a light bulb; if the bulb lights up, the material is a good conductor.

Front

Which element is NOT a conductor?

Back

Sulfur is NOT a conductor; it is a nonmetal and does not conduct electricity.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of chemical elements, organized by increasing atomic number, where elements with similar properties are grouped together.

Front

What are the properties of metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.
