Physical change - ANS-A change in the form of a substance, but not in its chemical

Distillation - ANS-A method of separating the components of a liquid mixture that
depends on differences in the ease of vaporization of the components.
Filtration - ANS-A method for separating the components of a mixture containing a solid
and a liquid.
Chromatography - ANS-The general name for a series of methods for separating
mixtures by using a system with a mobile phase and stationary phase.
Paper chromatography - ANS-Using a strip of porous paper for the stationary phase of
chromatography.
Compound - ANS-A substance with constant composition that can be broken down into
elements by chemical processes.
Chemical change - ANS-The change of substances into other substances through a
reorganization of the atoms; a chemical reaction.
Element - ANS-A substance that cannot be decomposed into simpler substances by
chemical or physical means.
Law of definite proportion - ANS-A given compound always contains exactly the same
proportion of elements by mass.
Law of multiple proportions - ANS-A law stating that when two elements form a series of
compounds, the ratios of the masses of the second element that combine with one
gram of the first element can always be reduced to small whole numbers.
Atomic mass - ANS-The weight of mass of atoms.
, Atomic weights - ANS-The weighted average mass of the atoms in a naturally occurring
element.
Avogadro's hypothesis - ANS-Equal volumes of gases at the same temperature and
pressure contain the same number of particles.
Cathode-ray tubes - ANS-The electrode in a galvanic cell at which reduction occurs.
The rays emanating from the negative electrode in a partially evacuated tube; a stream
of electrons.
Electrons - ANS-A negatively charged particle that moves around the nucleus of an
atom.
Radioactivity - ANS-Spontaneous emissions of radiation by uranium.
Nuclear atom - ANS-An atom having a dense center of positive charge (the nucleus)
with electrons moving around the outside.
Nucleus - ANS-The small, dense center of positive charge in an atom.
Proton - ANS-A positively charged particle in an atomic nucleus.
Neutron - ANS-A particle in the atomic nucleus with mass virtually equal t the proton's
but with no charge.
Isotopes - ANS-Atoms of the same element (the same number of protons) with different
numbers of neutrons. They have identical atomic numbers but different mass numbers.
Atomic number - ANS-The number of protons in the nucleus of an atom.
Mass number - ANS-The total number of protons and neutrons in the atomic nucleus of
an atom.
Chemical bond - ANS-The force or, more accurately, the energy that holds two atoms
together in a compound.
Covalent bond - ANS-A type of bonding in which electrons are shared by atoms.
Molecule - ANS-A bonded collection of two or more atoms of the same or different
elements.
Chemical formula - ANS-The representation of a molecule in which the symbols of the
elements are used t indicate the types of atoms present and subscripts are used to
show the relative number of atoms.
Structural formula - ANS-The representation of a molecule in which the relative
positions of the atoms are shown and the bonds are indicated by lines.
Space-filling model - ANS-A model of a molecule showing the relative sizes of the
atoms and their relative orientations.
Ball-in-stick model - ANS-A molecular model that distorts the sizes of atoms but shows
bond relationships clearly.
Ion - ANS-An atom or a group of atoms that has a net positive or negative charge.
Cation - ANS-A positive ion.
Anion - ANS-A negative ion.
Ionic bond - ANS-The electrostatic attraction between oppositely charged ions.
Ionic solid - ANS-A solid containing cations and anions that dissolves in water to give a
solution containing the separated ions, which are mobile and thus free to conduct an
electric current.
Polyatomic ion - ANS-An ion containing a number of atoms.
Scientific method - ANS-The process of studying natural phenomena, involving
observations, forming laws and theories, and testing of theories by experimentation.
Measurement - ANS-A quantitative observation.
