1.
a measure of the amount of matter that an object contains; the SI base unit of mass is the kilogram
2.
a measure of the space occupied by a sample of matter
3.
a property that depends on the amount of matter in a sample
4.
a property that depends on the type of matter in a sample, not the amount of matter
5.
matter that has a uniform and definite composition; either and element or a compound
6.
a quality or condition of a substance that can be observed or measured without changing the substances composition
7.
a form of matter that has a definite shape and volume
8.
a form of matter that flows, has a fixed volume, and an indefinite shape
9.
a form of matter that takes the shape and volume of its container; a gas has no definite shape or volume
10.
describes the gaseous state of a substance that is generally a liquid or solid at room temperature
11.
a change during which some properties of a material change, but the composition of the material does not change
12.
a physical blend of two or more substances that are not chemically combined
13.
a mixture that is not uniform in composition; components are not evenly distributed throughout the mixture
14.
a mixture that is uniform in composition; components are evenly distributed and not easily distinguished
15.
a homogenous mixture; consists of solutes dissolved in a solvent
16.
any part of a sample with uniform composition and properties
17.
a process that separates a solid from the liquid in a heterogenous mixture
18.
a process used to separate dissolved solids from a liquid, which is boiled to produce a vapor that is then condensed into a liquid
19.
the simplest form of matter that has a unique set of properties; an element cannot be broken down into simpler substances by chemical means
20.
a substance that contains two or more elements chemically combined in a fixed proportion
21.
a change that produces matter with a different composition than the original matter
22.
a one- or two-letter representation of an element
23.
the ability of a substance to undergo a specific chemical change
24.
a change in which one or more reactants change into one or more products; characterized by the breaking of bonds in reactants and the formation of bonds in products
25.
a substance present at the start of a reaction
26.
a substance produced in a chemical reaction
27.
a solid that forms and settles out of a liquid mixture
28.
in any physical change or chemical reaction, mass is conserved; mass can be neither created nor destroyed
29.
the smallest particle of an element that retains its identity in a chemical reaction
30.
the first theory to relate chemical changes to event at the atomic level
31.
a negatively charged subatomic particle
32.
a stream of electrons produced at the negative electrode (cathode) of a tube containing a gas at low pressure
33.
a positively charged subatomic particle found in the nucleus of an atom
34.
a subatomic particle with no charge and a mass of 1 amu; found in the nucleus of an atom
35.
the tiny, dense central portion of an atom, composed of protons and neutrons
36.
the number of protons in the nucleus of an atom of an element
37.
the total number of protons and neutrons in the nucleus of an atom
38.
atoms of the same element that have the same atomic number but different atomic masses due to a different number of neutrons
39.
a unit of mass equal to one-twelfth the mass of a carbon-12 atom
40.
the weighted average of the masses of the isotopes of an element
41.
an arrangement of elements in which the elements are separated into groups based on a set of repeating properties
42.
a horozontal row of elements in the periodic table
43.
a vertical column of elements in the periodic table; the constituent elements of a group have similar chemical and physical properties
