Study Notes

Particle Theory of Matter

Matter is composed of tiny particles.
Particles are in constant motion.
Particles have spaces between them.
The state of matter (solid, liquid, gas) is determined by how the particles are arranged and move.

Physical and Chemical Properties of Matter

Physical properties describe characteristics that can be observed without changing the substance's identity (e.g., color, texture, melting point).
Chemical properties describe how a substance reacts with other substances (e.g., flammability, reactivity with acids).

Chemical Changes in Matter

Chemical changes create new substances with different properties than the original substances.
Evidence of chemical change includes color change, gas production, precipitate formation, and energy release or absorption.

Classification of Matter

Matter is classified into elements, compounds, and mixtures.
Elements are pure substances made of only one type of atom.
Compounds are pure substances made of two or more elements chemically combined.
Mixtures are combinations of two or more substances that are not chemically combined.

Properties of Metals, Metalloids, and Nonmetals

Metals are typically shiny, good conductors of heat and electricity, malleable, ductile, and often have high melting points.
Metalloids exhibit properties intermediate between metals and nonmetals (e.g., semiconductors).
Nonmetals are usually poor conductors of heat and electricity, not malleable or ductile, and often have low melting points.

Subatomic Particles

Atoms are made up of protons, neutrons, and electrons.
Protons have a positive charge.
Neutrons are neutral (no charge).
Electrons have a negative charge.

Groups/Families of the Periodic Table

Elements within the same group (column) on the periodic table share similar chemical properties.
Group 1 (Alkali Metals) are highly reactive metals.
Group 17 (Halogens) are highly reactive nonmetals.
Group 18 (Noble Gases) are largely unreactive gases.
