What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Examples include Hydrogen (H), Oxygen (O), and Gold (Au).

Front

What is a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together. Examples include Water (H2O) and Carbon Dioxide (CO2).

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded. Mixtures can be homogeneous (uniform composition) or heterogeneous (distinct components).

Front

What is a mixture of elements?

Back

A mixture of elements consists of two or more different elements that are physically combined but not chemically bonded. An example is a mixture of Iron (Fe) and Sulfur (S).

Front

What is a mixture of compounds?

Back

A mixture of compounds consists of two or more different compounds that are physically combined but not chemically bonded. An example is a mixture of Salt (NaCl) and Sugar (C12H22O11).

Front

How can you identify a compound?

Back

A compound can be identified by its chemical formula, which shows the elements present and their ratios. For example, CO2 indicates one carbon atom and two oxygen atoms.

Front

What is the difference between an element and a compound?

Back

An element is a single type of atom, while a compound is made up of two or more different types of atoms chemically bonded together.

Front

What is the chemical formula for water?

Back

The chemical formula for water is H2O, indicating it is made of two hydrogen atoms and one oxygen atom.

Front

What is the chemical formula for carbon dioxide?

Back

The chemical formula for carbon dioxide is CO2, indicating it is made of one carbon atom and two oxygen atoms.

Front

Can a compound be broken down into simpler substances?

Back

Yes, a compound can be broken down into simpler substances through chemical reactions, unlike elements which cannot be broken down.
