Exploring Diversity of Matter and Chemical Composition

These flashcards provide key vocabulary and definitions related to the chemical composition and classification of matter.

Elements

Basic building blocks of matter, consisting of atoms and cannot be broken down into simpler substances.

Periodic Table

A chart organizing all known elements based on their atomic number, grouping them according to their properties.

Mixture

A combination of two or more substances that retain their individual properties and can be separated by physical methods.

Solute

The substance that dissolves in a solvent to form a solution.

Solvent

The substance in which the solute dissolves; it is usually present in greater quantity in a solution.

Concentration

A measure of how much solute is dissolved in a fixed volume of solvent.

Dilution

The process of reducing the concentration of a solute in a solution, typically by adding more solvent.

Suspension

A heterogeneous mixture in which solute-like particles settle out of a solvent-like phase over time.

Compound

A substance formed when two or more different elements chemically bond together.

Solubility

The ability of a solute to dissolve in a solvent at a specified temperature and pressure.

Chemical Properties

Characteristics that can only be observed during a chemical reaction, such as reactivity.
