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.
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 do you find the half-life of an object?
To find the half-life of an object, you measure the time it takes for half of the original quantity of a substance to decay. This decay process is typically exponential, and the half-life is a characteristic property of the material being studied. Scientists can determine the half-life experimentally by observing the decay of a sample over time.
Do hot vents have plant life?
no they do not have plant life.
What is incomplete life cycle?
A complete life cycle starts with seeds or birth, (plant or animal) and ends with death and decay.
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?
The rate of decay of a radioactive element is measured by its half-life, which is the time it takes for half of a sample of the element to decay. This measurement is used to determine the stability or instability of the element and to predict its rate of decay over time.
Why does radioactive carbon 14 begin to decay after a plant or animals dies?
Radioactive carbon-14 decays because it is an unstable isotope with a half-life of about 5,730 years. Once a plant or animal dies, it stops taking in new carbon-14, and the existing carbon-14 begins to decay at a predictable rate. This decay process is used in radiocarbon dating to estimate the age of organic materials.
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
What is the name for the length of time of a decay process?
The length of time for a decay process to occur is called the half-life. It represents the time it takes for half of the radioactive isotopes in a sample to decay.
Would decay be a functional characteristic of life?
Decay is not considered a functional characteristic of life. Decay is the breakdown of organic matter due to the activity of decomposers, such as bacteria and fungi. Life is more commonly associated with functions such as growth, reproduction, response to stimuli, and metabolism. Decay is a process that occurs after the cessation of biological functions in an organism.
How do you calculate the decay constant for a radioactive substance?
The decay constant for a radioactive substance is calculated by dividing the natural logarithm of 2 by the half-life of the substance. The formula is: decay constant ln(2) / half-life.
