Chapters 1-2
Anything that takes up space and has mass
What is matter
The smallest particle of an element that retains the properties of the element
What is an atom
An element that is generally shiny, solid at room temperature, and a good conductor of heat and electricity
What is a metal
That which is formed when two or more atoms bond covalently
What is a molecule
The SI base unit used to measure the amount of a substance
What is a mole
An explanation of a natural phenomenon based on many observations investigations over time
What is a theory
Negatively charged particles that are a part of all forms of matter
What are electrons
An atom or bonded group of atoms that has a positive or negative charge
What is an ion
A single covalent bond
What is a sigma bond
A ratio of equivalent values used to express the same quantity in different units
What is a conversion factor
A systematic approach to problem solving that uses conversion factors to change from one unit to another
What is dimensional analysis
A chart that organizes all known elements into a grid of periods and groups
What is the periodic table
The force that holds two atoms together
What is a chemical bond
An expression using chemical symbols to represent a substance
What is a formula
The study of quantitative relationships between the amounts of reactants used and the amounts of products formed by a chemical reaction
What is stoichiometry
A solid, liquid, or gas
What is states of matter
Atoms with the same number of protons but different numbers of neutrons
What are isotopes
A compound that contains ionic bonds
What is an ionic compound
A solid produced during a chemical reaction in a solution
What is a precipitate
Equal to a force of one newton per square meter
What is a pascal
This states that mass is neither created nor destroyed during a chemical reaction
What is the law of conservation of mass
A wave's height from the origin to a crest, or from the origin to a trough
What is amplitude
A three-dimensional geometric arrangement of particles
What is a crystal lattice
A polyatomic ion in which an element is bonded to one or more oxygen atoms
What is an oxyanion
States that the rate of effusion for a gas is inversely proportional to the square root of its molar mass
What is Graham's law of effusion
