Elements
* Definition: The simplest pure substance that cannot be broken down into simpler substances by ordinary chemical means.
* Examples: Gold (Au), Oxygen (O), Carbon (C), Hydrogen (H), Iron (Fe)
* Characteristics:
* Made up of only one type of atom.
* Found on the periodic table.
* Cannot be broken down further by chemical reactions.
Compounds
* Definition: A substance formed when two or more different elements are chemically bonded together in a fixed ratio.
* Examples: Water (H₂O), Carbon dioxide (CO₂), Table salt (NaCl), Sugar (C₁₂H₂₂O₁₁)
* Characteristics:
* Formed by the chemical combination of two or more elements.
* Have properties different from the elements they are made of.
* Can be broken down into simpler substances by chemical reactions.
Key Differences
| Feature | Element | Compound |
|----------------|--------------------------------------------|-----------------------------------------------------|
| Composition | Single type of atom | Two or more different types of atoms chemically bonded |
| Breakability | Cannot be broken down by chemical means | Can be broken down into simpler substances by chemical reactions |
| Properties | Unique properties | Properties different from the constituent elements |
In simpler terms:
Imagine building blocks. An element is like a single building block, while a compound is a structure made by combining different building blocks.
