What term used to describe rate of radioactive isotopes?
Half-life (in units of time).Half-Life is the rate of radioactive decay, measured in time. The half life gives the time it take for half of the radioactive atoms in a system to decay. Fore example, if you have 10 grams of carbon-14, it will take 5730 years for half of it to decay, giving you 5 grams. In another 5730 years, you'll have 2.5 grams left, etc...Isotopes decay at an exponential rate. A half-life is the time that half of the population of an isotope will decay. The measure is a statistical probability and is more accurate when a large population is observed. The term half-life is applied to describe a property of a given isotope (i.e. the half-life of Carbon 14 is 5730).half life
In chemistry what is a half life?
The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The concept originated in describing how long it takes atoms to undergo radioactive decay but also applies in a wide variety of other situations.Half-lives are very often used to describe quantities undergoing exponential decay-for example radioactive decay-where the half-life is constant over the whole life of the decay, and is a characteristic unit (a natural unit of scale) for the exponential decay equation. However, a half-life can also be defined for non-exponential decay processes, although in these cases the half-life varies throughout the decay process. The converse for exponential growth is the doubling time.
What would not be a functional characteristic of life?
Decay
Is the half-life of a chemical element one-half of the amount of a radioactive element to decay?
The half-life is the time that it takes for 1/2 of a material to decay.
How old in years is a fossil sample that has 12.5 percent C-14?
The half-life of Carbon-14 is 5,730 years. As such for the carbon-14 to decay from 100% to 12.5% it would take three times the half-life of the material.100% (1st half life decay period) 50% (2nd half life decay period) 25% (3rd half life decay period) 12.5%.Therefore = 5730 x 3 = 17,190 years.
What is incomplete life cycle?
A complete life cycle starts with seeds or birth, (plant or animal) and ends with death and decay.
To cause the remains of animal or plant life to decay?
In the SSW #20 the answer to #3 down is decompose
When was Life's Decay created?
Life's Decay was created in 2003.
The rate of decay of a radioactive element is measured by its what?
Any of the following can be used: the half-life, or the mean lifetime, or the decay constant.Any of the following can be used: the half-life, or the mean lifetime, or the decay constant.Any of the following can be used: the half-life, or the mean lifetime, or the decay constant.Any of the following can be used: the half-life, or the mean lifetime, or the decay constant.
Is decay a useful chemical reaction?
The decay of dead organisms in the soil makes the biochemical constituents of that organism more readily available for use by plant life; in other words, it turns dead things into fertilizer, and is a form of recycling. Therefore, it is useful.

What two outcomes can be expected as a result of an overabundance of aquatic plant life?
The plants will die and decay, causing a decrease in dissolved oxygen; plants will block sunlight to deeper water.
Where can I find more information on mulch?
Mulch is anything of organic plant matter that is put around other plant life so that it can decay and it's nutrients can be absorbed by the plant it surronds. more about this can be learnt by reading books about nature and gardening http://www.treesaregood.com/treecare/mulching.aspx
