When you jump into the world of chemistry, it's important to know the differences between elements, compounds, and mixtures. Here’s a simple guide based on what I’ve learned:

1. Elements:

• These are pure substances made up of only one kind of atom.
• Examples include hydrogen (H), oxygen (O), and carbon (C).
• You cannot break them down into anything simpler.

2. Compounds:

• Compounds happen when two or more elements join together in a specific way.
• For example, water (H₂O) is a compound made of two hydrogen atoms and one oxygen atom.
• Compounds have different properties than the elements that make them.

3. Mixtures:

• Mixtures are made up of two or more substances that are combined but not chemically changed.
• A salad is a great example—different ingredients like lettuce, tomatoes, and cucumbers all stay the same and can be separated easily.
• Mixtures can be homogeneous, like saltwater that looks the same throughout, or heterogeneous, like fruit salad, where you can see the different parts.

Keeping these differences in mind can really help you understand the basics of chemistry!
