Chemistry Definitions - Set 1

What is an atom?

• The basic particle from which all elements are made; the smallest particle of an element that has the properties of that element.
• The amount of space that matter occupies.
• The ratio of the mass of a substance to its volume. (Mass divided by Volume)
• Anything that has mass and takes up space.

• The ratio of the mass of a substance to its volume. (Mass divided by Volume)
• Symbols that show the elements in a compound and the ratio of atoms.

What is matter?

• A substance made of two or more elements chemically combined in a specific ratio or proportion.
• Anything that has mass and takes up space.
• the study of matter and how matter changes.
• A substance that cannot be broken down into any other substances by chemical or physical means.
