L- Lanthanides
- The series of f-block elements between
lanthanum and hafnium.
- laser
- Acronym for light amplification by
stimulated emission of radiation.A laser is an intense source of
light with a very narrow range of wavelengths. The intense light is
given off when many ions are stimulated and simultaneously emit a
photon at the same wavelength.
- lattice
- A regular arrangement of points in
space in 3 dimensions.
- law
- Mathematical statement of a
relationship that is always the same.
- leachate
- The solution produced by passing a
liquid through a solid, often containing chemicals that have
dissolved from the solid to the liquid. As rainwater passes through
landfills and associated sediments, various chemical substances may

- levorotatory
- Able to rotate plane-polarized light

- limewater

- liter
- Unit of volume in the metric system,
slightly larger than 1 quart, since 1 liter is 33.2 ounces, or 1
