Lanthanide Series |
The lanthanide series is one of two sets of inner transition elements. Elements 57 through 71 are a part of this series. The elements include cerium, europium, and holmium.

Lanthanum |
Symbol:"La" Atomic Number:"57" Atomic Mass: 138.91amu. Lanthanum is one of the elements in the lanthanide series of inner transition elements. It may also be classified as a rare earth element. It is the first element in the lanthanide series. It is a metallic element found in many minerals of the Earth's crust. You may also find it in catalytic converters and special types of glass (like lenses).

Law of Partition |
A situation that enables a solute to dissolve in solvents based on the solubility of those solvents. If you mix oil in water and add sugar, the sugar will dissolve more readily in the water because there is a higher solubility.

Lawrencium |
Symbol:"Lr" Atomic Number:"103" Atomic Mass: (260)amu. Lawrencium is one of the elements in the actinide series of inner transition elements. It may also be classified as a rare earth element. It is a radioactive and unstable element and you will not find it in use anywhere.

Lead |
Symbol:"Pb" Atomic Number:"82" Atomic Mass: 207.20amu. It is classified as a basic metal. Lead is a bluish metal found as an element and in many minerals. It has been used in several alloys, radiation shielding, and even insecticides. Lead is toxic to living organisms.

Limiting Reactant |
A limiting reactant is the limiting factor or element in a chemical reaction. If you have eight million hydrogen atoms and only one oxygen atom, you can only make one molecule of water. Oxygen would be your limiting reactant.

Liquefaction |
A process that increases the pressure on a gas until it becomes a liquid. This process happens at room temperature.
More Information: Liquids |
Liquid |
Liquids are an in-between phase of matter, between solids and gases. One characteristic of a liquid is that it fills the shape of any container. Liquids usually have a flat surface because of gravity pulling down on the molecules.

Liter |
A liter is a metric unit of measure for volume. One liter is equal to one thousand milliliters.

Lutetium |
Symbol:"Lu" Atomic Number:"71" Atomic Mass: 174.97amu. Lutetium is one of the elements in the lanthanide series of inner transition elements. It may also be classified as a rare earth element. You will find this element used in oil refineries.
