The Basics of Elements and Atoms

• Different substances have different properties, such as color and state of matter.
• There are different types of air particles, such as carbon, oxygen, and nitrogen, that have different properties.
• The smallest unit of a pure substance with specific properties is called an element.
• Water was historically considered an element, but it is actually made up of oxygen and hydrogen.
• All elements are listed in the Periodic Table of Elements, with each element represented by a symbol.
• The most basic unit of any element is the atom.
• Atoms are incredibly small and unimaginable in size.
• Carbon is an element and most living things, including humans, are made up of carbon.
• A cross-section of a human hair is a million carbon atoms wide.
• Breaking down an element into smaller and smaller chunks will eventually lead to its most basic unit, the atom.
• Atoms cannot be broken down further and still retain the properties of their element.
• Understanding the basics of elements and atoms is fundamental to understanding chemistry.
