Matter and Its Properties Quiz

Matter and its Properties

Matter is anything that has mass and takes up space.
Elements are substances that cannot be broken down into simpler substances by chemical means. They are listed on the periodic table.
Compounds are substances made from two or more elements chemically bonded together.
Mixtures are combinations of two or more substances that are not chemically bonded.

States of Matter

Solids have a definite shape and volume. Particles are tightly packed and vibrate in place.
Liquids have a definite volume but take the shape of their container. Particles are close together but can move past each other.
Gases have no definite shape or volume. Particles are far apart and move freely.

Physical Properties

Physical properties can be observed or measured without changing the substance's chemical composition.
Examples include color, odor, density, melting point, boiling point, and hardness.

Chemical Properties

Chemical properties describe how a substance reacts with other substances to form new substances.
Examples include flammability, reactivity with acids, and ability to rust.

Changes in Matter

Physical changes alter a substance's appearance but do not change its chemical composition. Examples include melting, freezing, boiling, and dissolving.
Chemical changes result in the formation of new substances with different properties. Evidence includes color change, formation of gas, precipitate formation, or temperature change.

Elements

Elements are the fundamental building blocks of matter.
Each element is represented by a unique chemical symbol.
Elements are organized in the periodic table based on their atomic structure.

Atomic Structure

Atoms are the smallest units of an element that maintain its properties.
Atoms consist of a nucleus containing protons (positive charge) and neutrons (neutral charge), and electrons (negative charge) orbiting the nucleus.
The number of protons in an atom determines the element.

Periodic Table

The periodic table arranges elements in rows (periods) and columns (groups or families) based on their properties and atomic structure.
Elements in the same group have similar chemical properties.

Atomic Mass and Atomic Number

Atomic number is the number of protons in an atom.
Atomic mass is the total number of protons and neutrons in an atom.

Chemical Reactions

Chemical reactions involve the rearrangement of atoms to form new substances.
Chemical equations represent chemical reactions, showing the reactants (starting materials) and products (resulting substances). Reactants are on the left of the equation, and products are on the right.

Introduction to the Periodic Table

The periodic table is a chart showing all known elements.
Elements are arranged by increasing atomic number. The atomic number is the number of protons.
Elements in the same group (column) have similar chemical properties.

Basic Chemical Calculations

Calculations can involve determining moles, mass, and volume of substances, or determining the stoichiometry of reactions. Stoichiometry deals with quantities in chemical reactions.
Using the periodic table, calculations can determine molar masses of elements and compounds.
