Study Notes
States of Matter
- Solid has a definite volume and shape
- Liquid has a definite volume but no definite shape
- Gas has indefinite shape and volume
- Solids have the least amount of kinetic energy
- Gases have the most kinetic energy
- Liquids have more motion than solids
- Kinetic energy is the energy of motion
- Gas particles have the highest kinetic energy
Building Blocks of Matter
- Atoms are the building blocks of matter
- Elements are pure substances made of one type of atom
- Molecules are two or more atoms bonded together
- Atoms in solids are tightly packed together
Types of Matter
- Elements are made of only one type of atom
- Compounds are two or more elements chemically combined
- Mixtures are substances that are not chemically bonded
- Water (H2O) is a common compound
Properties of Matter
- Physical properties are traits of a substance that can be seen or measured
- Physical properties can be seen without changing a substance's identity
- Metals are typically found on the left side of the periodic table
- Metals are usually shiny, malleable, and ductile
- Nonmetals are usually found on the right side of the periodic table
- Nonmetals are usually not shiny, malleable, or ductile
- Metalloids have properties of both metals and nonmetals
- Metalloids are found along the "staircase" on the periodic table
Other Properties
- Conductivity allows energy to flow easily
- Metals are good conductors; nonmetals are not
- Brittleness means easily broken or shattered
- Nonmetals are usually brittle
- Luster is shininess or reflectivity
- Metals are usually shiny and metallic, meaning they have lots of luster
- Malleability is the ability to be pressed into shape without breaking
- Ductility is the ability to be drawn into wire
- Density is the mass of a substance per volume
- Density = mass / volume
States of Matter: Continued
- Solids have a definite shape and volume
- Liquids and gases take the shape of their containers
- Matter can be divided into tiny particles called atoms
- Atoms have energy and are too small to be seen
- The energy of molecules in liquids is greater than the energy of atoms in solids, but less than the energy in gases
- Particles in liquids can move and flow
- Particles in solids vibrate in place but do not flow
- The kinetic energy of atoms in solids is much lower than the energy in liquids and gases
- Liquids take the shapes of their containers but gases usually do
