Element vs Compound
An element is a pure substance made up of only one type of atom, while a compound is a substance made up of two or more different elements that are chemically bonded together.

Element
- An element is the simplest form of matter that cannot be broken down into simpler substances by chemical means.
- Elements are represented by symbols from the periodic table, such as H for hydrogen, O for oxygen, and Na for sodium.
- Each element has a unique set of properties based on the number of protons in its nucleus.
- Examples of elements include gold (Au), silver (Ag), and carbon (C).

Compound
- A compound is a substance formed when two or more elements are chemically combined in a fixed ratio.
- Compounds have unique properties that are different from the properties of their constituent elements.
- Compounds can be represented by chemical formulas, such as H2O for water and NaCl for table salt.
- Compounds can be broken down into their constituent elements through chemical reactions.
- Examples of compounds include water (H2O), carbon dioxide (CO2), and sodium chloride (NaCl).

Summary
In summary, elements are the basic building blocks of matter that cannot be broken down further, while compounds are substances formed by the chemical combination of two or more different elements. Elements are represented by symbols from the periodic table, while compounds are represented by chemical formulas. Elements have unique properties based on their atomic structure, while compounds have distinct properties that are different from their constituent elements.
