Front

What is a nonmetal?

Back

A nonmetal is an element that typically lacks the characteristics of metals, such as conductivity and malleability. Examples include oxygen (O) and sulfur (S).

Front

What is a characteristic of metals?

Back

Metals are generally good conductors of electricity and heat, and they are malleable and ductile.

Front

What is a chemical change?

Back

A chemical change is a process where substances combine or break apart to form new substances, often accompanied by energy changes. An example is rusting.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals. They are often semiconductors, like silicon (Si).

Front

Which element is a good conductor of electricity?

Back

Copper (Cu) is a good conductor of electricity.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of elements organized by increasing atomic number, showing periodic trends in properties.

Front

What is the difference between physical and chemical changes?

Back

Physical changes do not alter the chemical composition of a substance, while chemical changes result in the formation of new substances.

Front

What is an example of a physical change?

Back

Melting ice is an example of a physical change, as it changes from solid to liquid without altering its chemical structure.

Front

What are some properties of nonmetals?

Back

Nonmetals are usually poor conductors of heat and electricity, and they can be gases, liquids, or brittle solids at room temperature.

Front

What is conductivity?

Back

Conductivity is the ability of a material to conduct electricity or heat.
