Five isotopes of zinc are stable; two have halflives of just over 240 days and just over 46 hours. 19 others are know; all have halflives of less than an hour and some less than a second.
See the related links for a chart with all of the isotopes and their exact halflives as known.

What rule did ozone play in the evolution of life on Earth?
Ozone is the one that formed life. Without it life would have been extinct.
What is the strongest force on the ozone layer?
In approximate order: # the presence of oxygen. # the availability of UV-C or more energetic light from the Sun. # the lack of other "permanent" acceptors of monatomic oxygen (to prevent formation of ozone). # the lower temperature (ozone has a half-life and increasing temperature increases ozone decay rate). # the lack of ozone decay pathways.
What is a cause and effect of ozone depletion?
Depletion of ozone is caused by CFC's. It is fatal to life.
How does ozone in the stratosphere affect life on the Earth's surface?
The ozone in stratosphere affects the life on earth. It protects and shields the surface of earth.
How might the ozone hole affect life on earth?
Ozone hole affects life. It causes the fatal UV to enter the earth.
How old is ozone?
Ozone has a short "half life", depending on where it is found, and the temperature where it is found. Liquid ozone has a half life of about a week. Ozone dissolved in water has a half life between seconds and hours (depending on water purity also). Ozone in air is also sensitive to contaminants in the air, such as water vapor... which help it to decay.
How long does ground level ozone last in the atmosphere?
A few hours. The half-life of ozone is dependent on temperature and water vapor, increases of either will shorten its lifespan.
Is there ozone layer when it is dark?
Yes. The "half-life" of ozone is several days at the night-time temperature of the ozone layer. So only a few ozone decay paths are present when sunlight is not available. what about nite with no daylight. Yes. During all times of day and variants of sunlight, the Ozone Layer is still present.
What is the life of an ultraviolet ozonator?
The useful life of the UV ozonator is limited by the service life of the UV lamp, and usually little else (since they are so poor in making ozone efficiently). It is common for low pressure UV lamps to lose half their intensity in 2000 hours or so. So after 2000 hours of continuous operation, half as much ozone is made.
What does the ozone layer protect life from?
Ozone layer protects life. It does so from UV's.
What is the physical state of ozone at room temperature and pressure?
The physical state of chlorine is a Greenish yellow gas with a pungent, irritating odor.
How can ozone affects your life?
Ozone acts as a shield on earth. It is present as ozone layer.
What would happen to life of earth if the amount of ozone in the ozone layer is depleted?
If the ozone in the ozone layer is depleted then, more UV will enter the earth. This will cause damage to life on earth.
What would happen to the life of earth if the amount of ozone in the ozone layer depleted?
If the ozone in the ozone layer is depleted then, more UV will enter the earth. This will cause damage to life on earth.
What would earth be like if the ozone was destoyed?
If there was no ozone, there would be no life. UV is fatal for life on earth.
How is th Ozone layer important to human life?
Ozone is important to human life. It is the most vital part of the life of organisms.
What rule did ozone play in the evolution of life on Earth?
Ozone is the one that formed life. Without it life would have been extinct.
