Neutrons
neutrally charged particles
Electrons
negatively charged particles
Cations
positively charged ions
Anions
negatively charged ions
Mass Number
sum of number of protons and neutrons in nucleus of an atom
Isotope
two or more forms of the same element (same number of protons) whose
atoms differ in number of neutrons, and in mass, with the same atomic
number and different mass number.
Quantitative
information such as numerical data
Qualitative
non-numerical data
Joule
related directly to units used for mechanical energy (1 cal = 4.184 J)
Precision
indicates how well several determinations of the same quantity agree
Accuracy
agreement of a measurement with the accepted value of the quantity
Solid
rigid shape, fixed volume, and changes little with temperature and
pressure
Liquid
fixed volume, takes on the shape of its container and has no definite
shape
Gases
volume of gas is decided by the container, changes in temperature and
pressure
Kinetic Molecular Theory of Matter
interoperates the properties of solids, liquids, and gases
, Kinetic Energy
energy associated with motion
Solution
homogeneous mixture of water and a dissolved substance.
Heterogenous
More than one substance
Homogenous
two or more substances
Elements
substances composed of only one type of atom
Atom
smallest particle of an element that retains the characteristic
chemical property of that element
Ion
electrically charged atoms or groups of atoms
Physical Change
change in physical properties, identity preserved
Chemical Change
one or more substances are transformed into one or more substances

Rutherford
gold foil experiment, conclusion that there are charged particles
Molecular Compounds
compounds that consist of discrete molecules at the particulate level
Ionic Compounds
consist of ions, atoms, or groups of atoms that bear a positive or
negative electrical field
Binary Compounds
"two-element" of non-metals
Compound
combination of two or more elements
Chemical Equilibrium
no further macroscopic change is observed
