Study Notes

Particles Composing Matter

Matter is composed of three main particles: atoms, ions, and molecules.
Atoms are the smallest particles; examples include hydrogen and oxygen.
Molecules form by bonding elements; common examples are water (H₂O) and sodium chloride (NaCl).
Ions are charged particles, which can be either positive (cations) or negative (anions).
Cations are formed by metals that donate electrons, while anions are formed by non-metals that accept electrons.

States of Matter

The four fundamental states of matter are solid, liquid, gas, and plasma.

Properties of Matter

Properties are classified as either intensive or extensive.
Intensive properties are independent of the amount of matter present.
Extensive properties depend on the quantity of matter.
Matter can be categorized by how properties are measured: physical properties do not change composition, while chemical properties involve a change leading to a new composition.
Pure substances maintain constant composition and are divided into elements and compounds.

Elements and Compounds

The periodic table contains 118 elements; 92 are naturally occurring, and 26 are synthetic.
Metals lose electrons, are malleable, and are good conductors of heat and electricity.
Non-metals gain electrons, are brittle, and are poor conductors.
Metalloids exhibit properties between metals and non-metals, often functioning as insulators.

Compounds

Compounds consist of combined elements in fixed ratios and can only be broken down through chemical changes.

Types of Chemical Bonds

Covalent bonds occur between two non-metals.
Ionic bonds form between metals and non-metals.

Mixtures

Mixtures consist of substances not chemically bonded and can be classified into three types: solutions, suspensions, and colloids.
Homogeneous mixtures (solutions) combine a solvent and solute, resulting in a mixture that appears uniform to the naked eye (e.g., salt in water).
Heterogeneous mixtures (suspensions) consist of distinguishable components that can be visually identified (e.g., oil in water).

Description

Test your knowledge on the fundamental particles that compose matter, including atoms, ions, and molecules. Explore different states of matter such as solids, liquids, gases, and plasma while understanding the roles of cations and anions. This quiz will challenge your understanding of the basic building blocks of the universe.
