Exploring Elements, Compounds, and Mixtures

What is an element?

• A type of molecule that contains multiple elements.

• An element is a pure substance made of only one type of atom.

• A mixture of different types of atoms.

• A substance that can be broken down into simpler substances.

Can you name three examples of elements?

• Water, Salt, Sugar

• Helium, Neon, Argon

• Hydrogen, Oxygen, Carbon

• Iron, Gold, Silver

What is a compound?

• A compound is a mixture of different substances.

• A compound is a type of chemical reaction.

• A compound is a single element.

• A compound is a substance made up of two or more elements chemically bonded together.

How is a compound different from an element?

• A compound is a single type of atom, while an element is made of multiple atoms.

• A compound is a mixture of different elements, while an element is a pure substance.

• A compound is made of two or more different elements chemically bonded together, while an element consists of only one type of atom.

• Elements can be broken down into simpler substances, whereas compounds cannot.

Can you give two examples of compounds?

• Water (H2O), Carbon Dioxide (CO2)

• Oxygen (O2)

• Sodium Chloride (NaCl)

• Glucose (C6H12O6)

What are mixtures?

• Mixtures are pure substances with fixed compositions.

• Mixtures are combinations that lose their individual properties.

• Mixtures are combinations of two or more substances that retain their individual properties.

• Mixtures are substances that cannot be separated by physical means.

What is one characteristic of a mixture?

• Components retain their individual properties.

• Components combine to form a new substance.

• Components lose their individual properties.

• Components can be separated by chemical means.

How do mixtures differ from compounds?

• Mixtures are chemically bonded, while compounds are physically combined.

• Mixtures can only be solid, while compounds can be liquid or gas.

• Compounds are made of one type of element, while mixtures contain multiple elements.

• Mixtures are physically combined, while compounds are chemically bonded.

Can you name two examples of mixtures?

• Water, Oil

• Sand, Gravel

• Air, Salad

• Sugar, Salt

What happens to the properties of substances in a mixture?

• The properties of substances in a mixture remain unchanged.

• The properties of substances in a mixture are combined into a new property.

• The properties of substances in a mixture are completely altered.

• The properties of substances in a mixture disappear entirely.
