Key Chemical Terms
- Element: A fundamental substance that cannot be broken down into simpler substances using chemical reactions. Elements are the basic building blocks of matter.
- Compound: A substance formed when two or more different elements chemically bond together in a fixed ratio, exhibiting unique properties different from its constituent elements.
Mixtures
- Heterogeneous Mixture: A type of mixture where the components can be visibly distinguished and are not uniformly distributed. Examples include salad and oil-water mixtures.
- Solution: A homogeneous mixture where one substance (the solute) is completely dissolved in another (the solvent), resulting in a uniform composition throughout.
Additional Concepts
