Verified step by step guidance1
Step 1: Begin by understanding the definitions of key terms related to the classification of matter: solution, compound, element, and mixture.
Step 2: Define a 'solution' as a homogeneous mixture where the components are uniformly distributed at the molecular level, often involving a solute dissolved in a solvent.
Step 3: Define a 'compound' as a pure substance composed of two or more elements chemically combined in fixed proportions, which can be broken down into simpler substances by chemical means.
Step 4: Define an 'element' as a pure substance that cannot be broken down into simpler substances by chemical means, consisting of atoms with the same number of protons.
Step 5: Define a 'mixture' as a combination of two or more substances that retain their individual properties and can be separated by physical means, such as filtration or evaporation.
