independent variable
The experimental variable that is changed during an experiment.
A substance that has a distinctly different color when in an acidic or basic solution.
A molecule which interferes with the function of an enzyme, either slowing or stopping the chemical reaction.
inner transition element
Element from the lanthanides and actinides series.
inorganic chemistry
Branch of chemistry that is the study of chemicals that do not, in general, contain carbon.
intensive property
Property of matter that depends only on the type of matter in a sample and not on the amount.
A species which appears in the mechanism of a reaction, but not in the overall balanced equation.
intermolecular forces
Attractive forces that occur between molecules.
International System of Units (SI)
A system of measurement based on the metric system and adopted by international agreement in 1960.

ion-product of water (Kw)
The mathematical product of the concentration of hydrogen ions and hydroxide ions in an aqueous solution.
ionic bond

ionization energy
Energy required to remove an electron from an atom.
ionizing radiation
Radiation that has the required energy to knock electrons off the atoms of a bombarded substance and produce ions.
An atom and an ion of a different atom, or two different ions, that have the same electron configuration.
Atoms that have the same number atomic number but different mass numbers due to a change in the number of neutrons.
