ionic bond
: A bond formed when charge particles stick together.
•
ionization energy
: The amount of energy required to pull an electron off of a 
gaseous atom.
•
irreversible reaction
: A chemical reaction in which the reagents make 
products but the products can't reform reagents. Most chemical reactions in 
basic chemistry classes are thought of as being irreversible.
•
isotonic solutions
: Solutions containing the same osmotic pressure.
•
isotope
: When an element has more than one possibility for the number of 
neutrons, these are called isotopes. All known elements possess isotopes.
For the record, the word "isotope" doesn't imply that something is radioactive.
TV told you that, and TV is stupid.
•
Kelvin:
A unit used to measure temperature. One Kelvin is equal in size to 
one degree Celsius. To convert between degrees Celsius and Kelvins, simply 
add 273.15 to the temperature in degrees Celsius to get Kelvins.
•
ketone
: A molecule containing a R-CO-R' functional group. Acetone 
(dimethyl ketone) is a common one.
•
kinetic energy
: The energy due to the movement of an object. The more 
something moves, the more kinetic energy it has.
•
Lanthanide contraction
: The tendency of the lanthanides to get small when 
you go from left to right in the periodic table.

•
lattice energy
: The energy released when one mole of a crystal is formed 
from gaseous ions.
•
lattice
: The three-dimensional arrangement of atoms or ions in a crystal.
•
law of conservation of energy
: The amount of energy in the universe never 
changes, ever. It just changes form.
