Ozone is a molecule of three bonded oxygen atoms: O3
Ozone and oxygen are a bit similar. Ozone is a 3 atom and oxygen is 2 atom.
Ozone depletion is the destroying of ozone molecules. These molecules are three atom. All the atons are of oxygen gas.
Ozone is created by the oxygen molecules. When the UV falls on oxygen, ozone is formed.
Ozone (O3) is produced when a single atom of oxygen (O) and a molecule of oxygen (O2) collide and join together.
Chlorine and bromine separate from the CFCs (chlorofluorocarbons) and destroy the ozone molecules. The chlorine and bromine atoms are not changed, so they continue destroying ozone. One chlorine atom can destroy up to 100,000 molecules of ozone during its lifetime in the atmosphere.
A chlorine molecule is very fatal to the ozone molecules. A single chlorine atom can destroy 100,000 moelcules of ozone.
Chlorine atom hurts the ozone. It depletes the ozone.
Each chlorine atom in the stratosphere can destroy thousands of ozone molecules, with estimates ranging from about 100,000 to over a million ozone molecules before it is removed from the atmosphere. This destructive potential is primarily due to the catalytic cycle that chlorine undergoes when it reacts with ozone (O₃), leading to its depletion. The significant impact of chlorine on ozone levels is a key reason for international efforts to reduce chlorine-containing compounds, such as chlorofluorocarbons (CFCs).
Ozone layer is confined of ozone molecules. These molecules form a huge pool of ozone molecules.
It's funny because I just read in my textbook, which was printed this year 2012, that one chlorine atom can destroy "ONE Million" ozone molecules. They do not explain why. It is more then likely goofball science that no one can back up. I'm no chem expert, but... Cl + O3 YIELDS destruction of (thousands/millions) O3 molecules. Yeah right.
Ozone molecules that absorb UV-B or more energetic light break apart, usually into an oxygen molecule and an oxygen atom. Sometimes the oxygen atom can recombine to form ozone again... if no competing reactions get to it first. Not sure what you had in mind about "something" absorbing ozone molecules... any chemical that ozone interacts with, gains the extra oxygen atom, leaving the oxygen molecule to go do something else. Even oxidizing elemental sulfur (or H2S), each oxygen atom consumed into the final molecule, breaks down one ozone molecule.
In the Spring, the earth tilts far enough toward the sun that the Chloroflorocarbons (CFCs) can be mobilized and become active. Once active, they attach themselves to the Oxygen molecules in the O2 gas -- ozone -- and the hole forms. A technical description from Wikipedia includes: "Ozone is formed in the stratosphere when oxygen molecules photodissociate after intaking an ultraviolet photon whose wavelength is shorter than 240 nm. This converts a single O2 into two atomic oxygen radicals. The atomic oxygen radicals then combine with separate O2 molecules to create two O3 molecules. These ozone molecules absorb ultraviolet (UV) light between 310 and 200 nm, following which ozone splits into a molecule of O2 and an oxygen atom. The oxygen atom then joins up with an oxygen molecule to regenerate ozone. This is a continuing process that terminates when an oxygen atom "recombines" with an ozone molecule to make two O2 molecules."
